Complain letter to a bank manager. Dear Sir, I am writing to you to complaining about a cheque book that I ordered from your bank two weeks ago, which to this day I have not received it yet. Let me point out that I am a business person who is needing to write cheques on a daily basis. I also inform you that this is the only account I have where I can write cheques. Due to those reasons it is urgent for me to receive the cheque book requested, as soon as possible. Otherwise, I will have to open a new account in different bank. I feel completely disappointed with the poor service your bank has provided me in this occasion, as I have had the urgent need to do some transactions which I have not being able to complete due your delay in deliver me a new cheque book. Finally, I will appreciate if you let me know by when I can expect to receive the new cheque book, and what are the steps you will take regarding this matter. I look forward to hearing from you soon. Sincerely,
