Lying and ignoring clients until they give up

I was charged twice for Box Office movies in October. I had issues with my account in December. My package gets changed without asking, then I have to pay to rectify it. I have called them, emailed them, complained on Hello Peter, but nothing helps. I am promised that they sent me a statement, which I never get. I am yelled at by a Call Centre agent. Every time I complain on Hello Peter, I am promised that I will be called or emailed or that I have already been called or emailed, but I receive absolutely no calls or emails from DStv. Seems like I am going to be **** to or ignored until I give up. I have never in my life experienced worse customer service from any other company. If you are not planning on doing anything, just don't reply to this complaint. I am tired of being **** to.
