Dear [Chairman],

It is with sincere regret that I feel I must write this letter to you regarding the unprofessional treatment I receiving from ----.

Since I know your bank to be one characterized by quality and service, this is now my fourth letter to ----. The previous three (copies are enclosed) failed to elicit any response from Bank.

I was unhappy with your service before the correspondence began, but that unhappiness has now been turned to anger by the way that your colleagues have ignored my letters. They clearly hope that by keeping silent, I’ll go away. Wrong. I’m now more determined than ever to make you honour your obligations.

The letter I sent to ---- on 4th November was written at Bank request. Bank wasn’t prepared to consider my points over the phone and insisted that I put them in writing. I was naïve because I thought that meant they intended to resolve the issue once they’d examined the evidence. What they really meant was: get off the line and get lost. Not only did Bank fail to do what they promised; Bank couldn’t even be bothered to acknowledge receipt of my letter or discuss my complaint.

From that time 4th November until the time of written this letters, I don’t receive any single call or letters explain what happen to my letters. I have tried many times to follow-up the status but customer service hasn’t any answers.

I will not trouble you with the details of the conversation, as it will serve no reasonable purpose. I am certain, however, that you will be concerned of the possible loss of business that may occur if customers are continued to be treated in this manner

Since I know you wish to uphold the good reputation of your Bank, I trust this information will be of interest and use to you, I’m afraid that ---- customer care problems are beyond solving, I’m relying on you to clean up the mess that your colleagues created.

I look forward to receiving your proposals to resolve this matter within the next 14 days.

Yours sincerely,
