Breach of contract

I phoned DSTV again today, to find out when I can expect my refund. Only to find out that according to them that my account is correct and they charged me correctly for premium service. How can i pay for something i never had. I never had the channels available. Please give my money back, as I signed up for a 24 month pricelock compact package with 2 pvr's for R598 per month. The funds additional funds debited from my account constitutes to theft and breach of contract. This was confirmed by youre representative that phoned me on monday. He said that the person that upgraded my package to premium was not allowed to. So please DSTV. September they deducted R751. I only reversed 1 month payment where the deducted R1902 October . November they deducted R1982,16. December they took R1017. So I am owed R1358.16 which was taken from my account *******ly. I dont want credit on my account. I want my funds returned to my account immediately. Dstv really sucks.
