DSTV PATHETIC SERVICE

I have phoned DSTV "helpline" in Durban 9 times to sort out THEIR problem. My mom installed a new decoder on 2/10/19 obviously with a NEW smart card number. They have NOT been able to do a simple task of transferring her account from one smart card to the next. Her subscription comes off on 1st of month and was PAID. They keep switching off her service saying she owes money. I phone then they switch it on for 3 days cause they can see she PAID but 3 days later it's off again. Can someone please EXPLAIN what the hell is wrong with DSTV.?????
