Multichoice does not care at all

Last month I was debited R400 more than agreed upon. When I called to find out what is going on, I was told that I called to change to a cheaper option, which I did not do, and then I was billed to change it back to premium. The call centre agent with a very bad attitude promised to email me my statement immediately, which I still have not received almost a month later. She said I never emailed to get my self service sorted out, but they gave the a wrong email address.. I was charged double for Box Office movies 4 months ago and I am still not closer to getting that sorted out after hours on the phone and many emails. I complained on the 28th of December and was promised to get a response within 24 hours, I am still waiting. Seems to me nobody at Multichoice cares about their clients. If this is not sorted out by the end of this month, I am cancelling by DSTV subscription and getting Netflix.
