Poor Service from MultiChoice and it consultants

28th June they deactivated my service saying I’m owning R823 of which I don’t where does it come from because I pay R629 each and every and my last payment was on the 31st of May where I paid R629. The following day the money changed from R823 to R773. I decided to pay it on 30th Of June even though I didn’t know what was I paying for because I wanted my TV working. 31 June they debit again R629 which means I have paid R1452. In one month while my service is R629. I then decided to call them on the first of August and their rude consultants one of them was Londiwe Bayeni who kept quiet as if she can’t here me when I asked about my situation for like 5min before answering me. They promised to reverse the money working 7 days but even today I haven’t received anything and when I call in the call center they put me on hold for like 10 minutes then come back with a response that they are still in process and today it’s the 12 of August which is way over 7 days because I called in on the first. I would also like them to go through every call I made and see how rude their consultants are towards clients.
