Unrequested PVR Activation with poor customer service

Last year October I got an SMS from multichoice saying that my pvr has been activated for free until December then when I made the month end payment the amount increased I called the call center and the guy said I should continue to pay my normal monthly installments and so I did today my dstv has been deactivated and I called again for two hours no one could help me instead the operater going back and forth asking the manager what to do she even took my number but the manager named Angel never called me back instead the operator apologized and said that the dstv would be activated once I pay the remaining balance of the activated pvr, I feel this is extremely unfair because I never agreed to activated the pvr in the first place and when I asked if there was anyone else that could help me she said no the way us to pay......is there anyone else to assist me with regards to this situation as this is pathetic customer service.
