Enough is Enough

This is my third review regarding MBD. They have not been truthful and not sorting out my account that was paid in full in which I was informed that was still owing to settle my Vodacome account. I have mailed them numerous time and no response. I was told my account will put put on zero when payment has been settled in full. When a company sends you a a letter stating this the amount that is what is till owing to clear your name. You do it but then nothing else gets done. I do not understood how we as customers can be treated like this.

What is my next step.

We are nothing to them just money in their bank.
