Dstv mutilchoice horrible service

I contacted mutilchoice call centre agent in May 2020 wanting to upgrade to dstv compact who told me about the special that they had whereby I was told that I will be paying R477 being on compact plus, she said that i was expected to pay R54,50 for updgrding which I later found that I was misled because I was expected to pay R90, 40.I was shocked when I got the message for the next debit order which was R629. 00.i contacted them 3 weeks ago and I was told by the agent that this matter is escalated to the team leader who I spoke to and she promised to listen to the recording for that particular conservation and will come back to me. Till to date I am still wanting for the answers but no one called me. I am so disappointed to receive this terrible service from the company of this caliber.
