Worst customer service

We are, no were, loyal DSTV customer for years up to now. But the bad service, poor communication and ********* behaviour forces us to cancel our DSTV subscription. We are being billed for services we have not requested; a fact has been verified by two separate call centre agents. Despite this, the amounts have not been reversed, and for reasons that have not been explained to us. We have tried repeatedly to resolve this issue, and have been told that the case is 'escalated' and being attended to. The last call centre agent I spoke to even told me that our access will not be affected while the issue is being looked into. In the meanwhile, we have of course refused to pay for something we have not requested, and now our service has indeed been cut off. Incidentally, according to your automated call centre, our account is in credit!!!!! Any attempts to try and find out what is going on have been met with deaf ears. NO RESPONSE! So, no thank you DSTV. We refuse to be treated so unfairly.
