Not satisfied with any service from DStv Price Lock or DStv Rewards

Didn't get any help it just got worse. My bill went from R800 to R900, I'm being charged for installation, and Access fee, which was supposed to be free. Not satisfied with anything from DStv price lock and DStv rewards department took away thr rewards i was supposed to get. I've queried about it numerous times, but rewards department is ignoring me. And i was told i never paid, but my account is being debited every month. The fault is on DStv side, payments and everything.
