POOR service

I phoned Multichoice beginning end of January to switch my DSTV off so they switched it off. Beginning of February a week after I asked them to switch it off I phoned to switch it on again which they asked me to pay R697 so I asked them to debit it that Monday which didn’t happen, we went away to Cape Town for a week and when we came back it was still off. When I phoned yesterday she told me I have to pay R1099 before switch it on WHY did the price change and still my DSTV is off after I asked them to deduct it yesterday. I tried phoning more than 20 times no answer. poor service and no explanation for the price which I have to pay now...
