Pathetic call centre agents and waste of time rewards programme

I received a reward for an upgrade to the premium package. After numerous calls to the worst customer service agents in the world I kept getting disconnected. One call was over 30 minutes and today was more than 45 minutes trying to explain the terms and conditions which are from DSTV themselves which state that the upgrade incurs no additional charges. The agents do not listen to the query you have. They just give you robotic responses. I spoke to the call centre supervisor who asked for a screenshot of the reward which was emailed to her. She stated it would be activated but it never did. When I called to query it I am told to resend the screenshot and that I have to pay in half of the premium package. It is frustrating to try and get a resolution as they keep cutting the calls when they cannot get their way.

They also have an anniversary reward which supposed to be activated automatically and deactivated after 30 dyas but that doesn't happen either without the customer calling and requesting it to be done. I have an unresolved query regarding incorrect billing as well. They should s**** the rewards programme as the left hand does not know what the right hand is doing.
