Dstv I want all my money back

I am disgusted by the treatment from dstv. I got a notification that owe R1368 which ai do not. I queried via twitter and the consulted confirmed that it's an error which wil be fixed asap. Nothing was done and I went to Randburg customer care where a consultant confirmed it was their error and she escalate it to their account department. I have emailed them twice and still no response and they just debited R1368 off my account. I want my money back, this is an inconvenience. I do not owe dstv a cent. My account is always debited monthly, I've never missed payment and as far as I know when you do not pay dst, they disconnect it so why would I be watching dstv for all this time if i owed them?
