Unhappy Multichoice (Dstv) customer

I have called and asked many times for my statement as monthly subscriptions keep changing - being on Compact I get billed in excess of R700 . I gave them 2 diff email addresses and still no billing sent to me to explain their charges. When I call in they say I owe them - for what ??? Bec if bill not paid (in advance) services are terminated. They are *********** consumers and when we ask for explanations the managers are busy, in meeting and even on lunch . I have called them almost every month with same queries and still no resolutions . So I stopped subscription for a few months and when call to reinstate - I get an amount from the consultant , pay it and call back bec still no service. To be told sorry you still owe R42 as in my most recent call to them . I have been Dstv customer for over 20 hrs and now they are now a ******* with inexperienced consultants .
