Got overcharged

On the 4th of August I phoned Multichoice to downgrade my service from Premium to Easyview. The call centre agent confirmed that the downgrade had been scheduled. I then didn't get downgraded but was away for most of the month. On Thursday the 20th of August I got completely disconnected for not paying my outstanding bill of more than R700. On Friday the 21st of August another call centre agent phoned me to tell me the outstanding amount I needed to pay to get connected again. I explained the situation to her and she committed to sorting it out for me and that she would get back to me that day still. This never happened and I am still without any form of DSTV....not even Easyview. They also haven't emailed me my bill. So I don't know what to do except complain about the bad service on hellopeter.
