NON existent client service

My price lock ran out, no one from DSTV contacts me, they just cut off my viewing, this AFTER the debit order for the coming month has already gone off. I phone them and the say just pay the outstanding balance. So we organize that the extra R55 or so goes off with the next debit order. A week later, my DSTV is cut off once again... phone into customer care, same story, same arrangement. Then a few days later I receive a message that the next debit order will be for R1223 and some cents. Once again I phone customer care, only to be told that the amount is that high because of pro rata billing, BUT YOUVE ALREADY BEEN PAID BY DEBIT ORDER FOR THE MONTH SO ONLY R55 SHOULD BE ADDED TO THE NEXT DEBIT ORDER!!!!!!!!! So how the heck do you bill me again for a month that has already been paid for????? By now I have had enough of your incompetence and I cancel my DSTV subscription, and since I cancelled it in the month that has already been paid for, According to your consultant, I only had to pay the outstanding R55, which I did. Well, to my surprise I see that even after cancelling my DSTV, the debit order for the R1223 still went off. I want this sorted out and the money erroneously debited from my account paid back immediately. I have the email communication from your consultant stating that my DSTV was cancelled and that i will not have DSTV from the 27th of July. well its the 27th of July, my dish is still working and you took the money. YOU did not do your JOB, and I will NOT pay for YOUR mistake. I want my money returned to me IMMEDIATELY.
