DSTV cut my signal two times and i am paid in adva

I have a DSTV account a week ago i got home and my dstv signal was disconected there is no person to talk to over weekends and you are stuck with a computerised voice on the other side with no help at all. went the whole weekend without dstv and i was informed that they went on a new billing system and was cut of by mistake they even charged me R50 rand reconection fee even thoug it was their mistake. THey conecoted my services again and it was working again. Yesterday got home and the same story again they do not even give attention to you on their facebook page if you ask for help. I on earth can a company like DSTV do this to the customers there is thousands of complaints on facebook regarding the same issue. When you tell them you want to be refunded they get very coky with you. Please Please help me with this problem i am having.
