Account query

DSTV will give you a month free then months later you get a bill that is double. I've called and was told the manager/team leader will credit my account, a week later it hasn't been done. I have been calling their call centre and the team leader I spoke to when my call got cut, she didn't even bother to call back, I called again and was put on hold for over an hour. DSTV doesn't even deserve 1 star, that's why people move to the likes of Netflix
