Double billing

Multichoice has double billed me for two months in a row and every time I try to contact them they transfer me to someone else. Someone has promised to call me back and she never did. This month I paid R518 for my compact, extraview and pvr functions but today my service were disconnected and when I raised the matter I was told to pay R563 more. It's shocking that I have to pay more than a thousand rand for a compact package. My services are still disconnected as I write this. Multichoice agents do not know what they are doing there. Useless!
