Customer Complaint Letter about an Employee

Dear [Manager Name],

I would like to file an official complaint against one of your employees. I believe you have right to know what kind of people are working for you and how negatively they affect your business. This is not the kind of treatment people would expect from a prestigious organization like yours.

[Tell your story here. What, when, and where it happened? Who is the employee? Support your case with numbers, dates and facts.]

I'm confident that you agree with me that such behavior is totally unacceptable under any circumstances. I'm reluctant to have any kind of business with your company in the future and I really do hope that you will take all the necessary precautions to ensure that such incidents do not happen again with other customers. This is this just not good for your image and your reputation.

Regards
