DSTV - Bullies Customers to paid up for services of thats their mistakes

Dstv_ are continuning over billing my account and when you call their call center you get the run around. I was promise a called back from them last week and never received a massage or a call so far. this month they want to charge me for again over 2000 rand. I don't think they concider that they are bad service providors, They are only here to skin as dry, this is not the first time I have a problem with their service....Switch my service off and going somewhere else... that's why they are lossing customer in Africa....
