DSTV - Really bad service with regards to an account query

I have been trying to rectify my account with DSTV for three weeks now, every time a so called case is escalated and nothing happens - I am a premium customer with one main decoder and extra view, I normally pay R849 per month - all of a sudden my premium jumped to R1808.00 and no body can tell me why - problem is the call centre cannot assist and keeps on escalating to who knows who and there is nothing being done - I am frustrated and angry with their ignorance to their clients - how can nobody help me????
