Incorrect Billing and messed Account

I'm tired of contacting Dstv to correct my account, I have called them this morning to find out why my PVR option is not working and was it will be sorted in 3 hours which in not the case and I now cannot view any channel yet my account is active. It's been a month since my account is messed and if they really valued me as the client it could have been sorted one time but instead the amount keeps flauctuating and no one can explain how and why. I'm seriously considering just cutting my business with Dstv because it's really not worth the trouble
