Multichoice falsely charging customers

Multichoice keeps on charging me extra. A few months ago I had to pay extra and I went to multichoice to enquire and I was told that they are charging me for insurance which I did not take. I told them to cancel it and was told I still had to pay the insurance for that month and I did and told them to cancel it. Now this month I was paying and I paid extra with R80 than the normal fee for my DStv subscription because my payment was a day late and I knew I had incurred extra charges but still I was not reconnected. I woke up today and went to a Multichoice branch and was told that I have Insurance and I have to pay an extra R217.93. I tried calling the call centre for close to 30 minutes and there was no one answering. I asked the people at the branch to call the call centre for me and they told me they can’t help me with that.
