Multichoice is a joke

I requested them to de activate my services on the 1st of November 2016 and when I called in July to get my services activated I was advises that my balance is R250 because they debited my account and I revesed it. When I called in July they told me that my services was activated after I had requested deactivation without my consent. I went to one of the Multichoice branches in Port Elizabeth and was told this matter will be escalated and the amount would be removed. They activated my services and sometime in August they switched it off again saying I have an outdtanding amount. I called again and was activated again. I called now on 2nd September for an upgrade and was told to pay R399 for Compact. Wednesday morning they deactivated it again and I made payment Thursday night and called them but again I was told about this R250 outstanding I was told to send proof of payment and I did so but nothing's happened. I calles them now again and they are still telling me about the same amount and their supervisors are always in a meeting. I have had it with these people trying to get money from me over something they made on error. I have spent soo much of my time and money calling them but getting absolutely nowhere with them I am sick ans tired of Multichoice and their useless service.
