DSTV useless

Beginning of this month I called and told them that I need to cancel because I will not be able to watch it for the next 3 months. The lady I spoke with said I need to pay R258 if I need to cancel, and I indicated that they have already deducted for January. Today I get message to say I need to pay R539. When I phone again today, they said that lady did not cancel and R257 was pro rata to keep on watching. My question to them is why will I cancel if I want to keep on watching, does it make sense to them. I need DSTV to refund my money back and I do not think I will ever go back to DSTV their service is bad. Not to mention the *********** lady
