Apology Letter for not Picking up the Call

Sample of apology letter to friend for not picking up his call earlier due to being busy and now inviting him to hangout some other time.

Apology Letter for Not Calling Back

Dear Mr. Anderson,

I would like to formally apologize for missing your call the other day and not calling back. I was caught up at a parent-teacher conference at my daughter’s school and I was not free until late at night, at which point I did not want to disturb you by calling.

I hope we can catch up later today; we can grab a coffee and have a chat if you wish.

Waiting for your response,
Mike Irvington

Apology Letter for Not Calling Back

 Dear Uncle,

I hope you are doing well. I am fine too. I sent this letter to apologize for not answering your call last week and for no response later on. Actually, I had my exams of second semester and when you called me I was in the classroom so could not answer it and then later on I got so busy with the exam preparation that it totally slipped my mind. Due to my packed schedule these past few days, I have not been able to get touch in any one. On the brighter side, I did quite well in my exams and am hoping for a good GPA.

I miss you all a lot and am planning on coming back to meet everyone this winter vacations. Give my greetings to Aunt and lots of love to Little Fatima.

With love,

Fatima Noor

Apology letter for not calling back

Dear Anna,

How are you? I hope you are doing well. How’s everything at home? Yesterday, when I got back from my job and checked the home phone I saw that you had called. I am so sorry for not being able to attend your call. I was so tired that I wasn’t able to call back and just went to bed. Lately, things have been so busy on my side. Managing my job, the house and the kids is very difficult and tiresome. I barely get any time to call my friends and family which is so upsetting. When I come back from my job I try to spend some time with the kids and my husband. After that I set up dinner and then go to sleep. I will surely call you on the weekend and we’ll have a long chat.

Once again I’m sorry for not calling back.

Best Regards,

Fatima Waqas

Application for Lost Library Book

Dear Librarian,

I issued a novel from library last week and today was the due date to submit it back.

Application for Lost Library Book

 Respected Librarian,

With due respect, I issued an SAT book last week for my test preparation. Yesterday, I brought the book with me to the school for returning it. However, during my free class when I was in the ground, I forgot the book over there. When it came to my mind that I have left the book in the ground, I immediately went back but it was nowhere to be found.

I went to the lost and found office, but the in charge didn’t receive any book on that day. Also, I asked other people who were there in the ground at that time but nobody saw it. I am sincerely sorry for disappointing you. You can look into my previous issuing history and such thing has not happened even once and I always used to return the books in time.

I am aware that you are disappointed with me for being this irresponsible. I am ready to pay the fine and I request you to kindly let me borrow books from the library in the future. I assure you that such thing will not happen again. I hope you accept my apology.

Best Regards,

Application for Lost Library Book

Respected Sir,

With all due respect, I am writing this application to inform you that I have lost one of the library books that I issued last week. I issued three books out of which one of them is lost. I have searched in all places but I cannot seem to find it anywhere. The book’s name was ‘The fault in our stars’. I am well aware with the library’s policy that if a book is lost then the borrower can either pay the amount for the book or replace the book with one of their own copy. I will drop by the library tomorrow and pay the amount for the book. I am very sorry that such an incident has taken place. I promise you that it will not happen again.

Please do excuse me.

Apology Letter To Customer For Poor Service


Mr. Ali Shah

Respected sir,

With all my sincere respect, I am writing this letter to make an apology for the delay in processing your request. I know how disturbing it is to not get any response when you have paid for a good in advance. Let me explain you my side sir.

Due to the heavy rain fall from last month internet service is not working properly and we are unable to contact to our dealers. Because of rain the courier service is also not available in most of the areas. We have got your order and we will dispatch it tomorrow. We really appreciate the patients you have got. I request you to accept my apology and give us another chance to serve you. We are again really sorry for the delay and will be thankful to you if you give us another chance. Thank you.

Yours sincerely,



Apology Letter To Client for Delay in Service

 Dear Client,

Three days back you booked our delivery services for delivering you the furniture you bought from Ali Furniture, which is located in Defense, to your house.

We were going to pick up the goods from the outlet and deliver it to you next day but unfortunately, the weather was really harsh so we couldn’t send our boys to fetch the items. Due to the heavy storm, the roads were flooded and it was still not safe on second day so the service was again delayed. After the weather was better and roads were a bit cleared, I immediately send the workers to get your items delivered.

I am really sorry for the inconvenience caused by this unexpected situation but as it is something natural and not in our control so I cannot do anything to prevent this from happening in future. I am also thankful to you for understanding the situation and not cancelling the orders. We hope you will continue to choose us in the future too for delivery service.

Apology Letter to Client for Delay in Service

To: Jose Alexanderson
Blackcreek County, Montana, United States

Dear Jose,
I understand that you are looking for a home as quickly as possible, and I wish to convey my deepest apologies for the delay in service.

I assure you that I am working extremely hard to sell your home. As we are in the midst of a recession, the housing market has hit a low. There is not much demand for these kinds of houses, especially in Montana which is more of a state for tourism than a state to reside in.

Again I apologize for the delay, please understand that I am doing the best I can in these conditions and I guarantee that I will find a buyer soon enough.

Tomorrow we will send in one of our employees to receive the items you ordered and they will be compensated by new ones. You do not have to pay for them. Normally, such situations do not happen with our services and I am sorry you had to witness this.

I hope you will excuse this service of ours this time and continue ordering from our company.

Dear Mr Eric

I feel remorseful for the inconvenience that happened last night. There was a birthday party at our place due to which the children were playing loud music. I was not at home to stop them from making such a racket. When your wife came at our doorstep to complain about the loud music the kids ridiculed her, and I am really sorry for that. I know it is not a good gesture. Being a resident of this society it is my responsibility to take care of my neighbor’s rights. I am writing this letter to you to apologize to you for the misbehavior of my children.

I, on behalf of my children, apologize from the core of my heart. I will also send my kids to your house to personally say sorry to your wife.

We have always been good neighbors and I do not want to spoil our good relations.

Accept my apology whole heartedly.

 Email for delay in project submission


We apologize for the late submission of your project. It was a huge challenge for our group to complete our project within the given deadline. We were going with good pace and the project was meant to be completed in the given time but then one of our group members fell seriously ill. He remained in the hospital for three years. Due to his absence the task of writing was totally disturbed and that ultimately culminated in late submission.

We are hard working students and have never made any lame excuse. I request you to accept our project. Our annual result relies on this submission. It is a matter of our career. We cannot afford to have bad grades in our final results.

Expecting your cooperation.

Thank You

To the respected principal Mr. Blackford,

I am writing this letter to formally apologize for my behavior in the past week. I have not been following the school rules, and this was a grave mistake on my part. I deeply regret my past actions and I, without a doubt, will not engage in this behavior again. I promise to respect the school, the rules of the school, and my respected teachers. I will engage in class and follow all school rules, and you will never receive any complaints about me again. I ask that you accept my apology and give me another chance so that I may redeem myself and prove that I can be a better student in the future.

Apology letter for violating school rules

Dear Bilal,

I am writing this letter to you with much disappointment. Recently, I received a complaint regarding your behavior in school and I was very shocked by this. I contacted the person who wrote me the letter to confirm if they were mistaken. You are an outstanding child in your academics, extra curricular and your behavior. You are one of our institute’s star students. I have been told that you violated the school rules by misbehaving with several teachers and students. A fight was also reported to me, which you started. I am not sure why you are acting this way but I want you to stop. If there is anything bothering you, please do let me know and I will help you out. Since you are one of our good students, I will deal with you leniently and let you go with a warning. If such an event is reported again, I am afraid you will be suspended from school and we will have to call your parents as well.

I expect that such an occurrence will not happen again.

Best Regards,

Complaint letter to Airline for Delayed Flight


The manager, Air Asia

Respected sir,

I am writing this letter to make a complaint regarding your flight delay of air bus 308 from Lahore to Frankfurt. It is not the first time that we are facing such issue. Passengers buy expensive tickets because they have important work to do or to be at their desired place for any important reason. But I guess you people do not consider our engagements or tasks important.

I had a very important meeting to attend which I could not because of your poor service. This is not a professional way to deal with your passengers. We are not paying a handsome amount for such blunders. If we are paying well to your airline we expect quality service. The flight was delayed without prior information and we had to wait at airport for 8 hours. No one of the staff member was cooperating with us. I am really sorry but you have lost your quality. I am never going to travel with your airline again. This was my last and worst experience. Thank you.


Mr. Tahir Malik

Complaint letter to airline for delayed flight

Respected Sir,

With all due respect Sir, I am writing this letter to inform you about my experience with your airline.

I had a flight a week ago from Pakistan to Turkey. A very important business meeting had to take place that day and I was flying in a few hours before so I would be able to attend it.

However, such was not able to happen. I was in the waiting lounge ready to board my flight when I got a notification on the screen above me that my flight had been delayed. I was alright since it had been delayed only for a few minutes since the aircraft crew was not ready to fly. I waited for the flight to board but I got no such notification. After an hour or so I got to know from the management that my flight had been delayed for three hours. When I questioned the management why this had happened they gave me no such convincing response and asked me to be patient. I was very disappointed since I had to miss my meeting and was never provided with a reason as to why the flight had been delayed. If I had not gone to the management myself I would have never known it has been delayed this much.

I hope such an event will not happen again and relevant actions will be taken against my complaint.

Dear manager,

I am writing to you because I would like to formally apologize for sleeping on duty. I would like to say that it was down to me not getting any sleep and that I will go to bed early to make sure that I get enough sleep for work but that is not the truth. The truth is I have been sleeping but I haven’t been sleeping well.

I sleep walk and recently it has got worse like I wake up in the middle of the night miles away from my home. I get night terrors and wake up suddenly.  I can say that the doctors have given me an option and I’m going to take it. It is some surgery on the sleeping part of the brain.

After a few months of recovering I will be better. So again I am very sorry and I can tell you that it won’t happen again. Please forgive me.

Yours sincerely,
