Owing Credit not paid - poor customer service

I terminated my DSTV premium package on 29 June however the debit order for August still was deducted (timing issue). When I made contact via the customer email, I was informed that their systems were being updated and that they would respond in 2 weeks time. After that period, I sent another email to pick up the issue. After numerous emails of either no responses or generic unhelpful responses, I resorted to phoning the call center which initially was a pleasant experience. I was told that my account had been reactivated in error during the system upgrade. The credit was raised and I was promised that the money would be paid back into my account over a month ago. After numerous further calls (at a premium call cost) without resolution, I have asked on 3 occasions for a supervisor to call me which too has never happened. I am now recently told that they credit was approved and passed onto my DSTV account (not my bank account) however instead of <br> R830.93 credit due, my online statement only shows R79. I phoned back today and was put on hold for an exceptionaly long period until I hung up. Please check all the call logs and call me back to resolve. I want the money paid into my bank
