Dstv poor service for unallocated payments

Since beginning of December I've been calling Multichoice for the December payment that is not allocated. I've forwarded them the receipt 3 times, they kep saying their payments department will call me at first, of which they never. And the other consultant told that this issue can take a year as my issue has been escalated globally.

Every week I must call them for the same issue. It is really disappointing for the company that is big as Multichoice take this long to resolve us an incident. It's as if they don't care about you as the customer. And when you contact them you have to explain the same thing over and over. And keep sending them the same receipt as if you are trying to **** them or something. Their system are so bad that they can't even check on their system that you reported the same issue before, it's so irritating. I find them so arrogant as the company that doesn't have a competition.
