I am very irate and frustrated and this moment

I am writing to make a formal complaint against Noni who I believe is a Manager or supervisor in the customer service.My complaint is that they failed to provide me with a satisfactory service when I was doing a follow up on the refund that has passed the turn around time.

I believe that dealing with customers means you have to control your own emotions, and to counteract inflammatory behavior with calm, but that’s impossible to your employees.

Please lodge my complaint against her and make sure I receive my refund as in yesterday,it’s long over due now and this is so unnecessary and frustrating.
