DSTV not living up to your promises

DSTV (MultiChoice) decived me to come back to them , they sent me a special informing that if I can come back I will able to pay only R215 X 3 months . I even received a call and i accepted I paid R215 last months now I need to pay for this months I got qouted R527 and I asked what is that for , 3 agents just told me they is a technical error , Now they have reduced to R485.00 now they no longer talk about R215. I feel like I have been ****med to come back to DSTV.I was promised that this will be fixed until now ..If they dont assist and tell me what to do , I mighty as well cancel the DSTV and DSTV mighty as well consider another client gone . I only subscribe because of soccer . I will find another way. Am dissapointed on DSTV
