Worst service in the world theyre too big for their client

Dstv is in competent i regret why I did this pricelock think i have the day i did it. They billed me wrong on September with R1500. I called the call centre over 5 tomes to help me the locked calls to finance promising me to be called no one ever did. I then told them im gonna reverse till they called no one called. Month 2 still the same thing no one could explain from the call centre i asked for a call to be logged to finance still nothing. I reversed and told them everytime the bill wrong ill reverse no one did. 3rd month same thing.then I went to the service centre the switched me back on and told me thell fix and get someone to call to arrange to pay the right amount no one did. This company hates their clients i dont know y they even exist. No one can add it me at call centre they give me bombers to sms nothing happens. So im so stuck. My id number is ***.
