Complaint Letter To Bank

Dear [Customer Service],

I'm writing this letter to express my disappointment from the unacceptable service I've received from your bank. One would certainly expect a much better treatment given your prestigious status and your over advertised “customer focused policy".

[Mention your problem here. List numbers, dates, and facts]

I kindly ask you to look into this matter and take the necessary actions to resolve it. [If you have specific demands, mention them here].

I'm waiting for a reply from your side, preferably with satisfactory solution. I also hope that your bank will make amendments to ensure that such incidents don't happen again.

Regards
