Very very poor service

For the past 3 days have been trying dstv call centre agents to fix my dstv now app as it only gives me only 8 channels whereas I am a premium subscriber. The agents have completely failed to fix my problem and i have spoken to several different call centre agents and all seem to not have a clue of solving my problem. I have sent emails about the issue and they have failed to fix it. I have been told to log out and log in but there is no change. I have tried even changing my password but it always gives a 404 error which I have sent to them and they have failed to fix it. This is a very disgusting and disappointing service from multichoice.. I hope there is someone who can help urgently. If I had a choice of a different service provider by now I would have cancelled my contract even if it means I have to pay off my contract with them. This is very bad. Personally I would like to give them a zero rating.
