Total silence for three days.

I have been waiting three days (since 7.12 Wednesday morning, it is now Friday night) for DStv to contact me. Any kind of contact. Although I prefer not to be telephoned, it doesn't provide a record. (I have nevertheless twice been promised a call back during the three days. Never happened.) I have a 24 month subscription that is less than half completed. But I have been cut off two months running because my payment card was lost and replaced, so wasn't paying my monthly subscription. I was also fined R50 each month for reconnection. After I used my new card to pay. But do you think MC's antiquated and buggy accounting system could pick up my new card details? Of course rse not. So will DStv simply tell me what I have to fix this, as I have asked in emails and calls? Of course not. They can cut me off next month and charge for another reconnection. MC wonders why Premium subscribers (as I am) are leaving in droves?
