Outrageous Account & Lack of Response

I cancelled my Multichoice/DSTv a very long time ago due to the nonsense they show, adverts I pay for & repeats and very old content. Since cancellation, they have owed me R130. To try get anyone to respond is beyond possible, and at no point (despite requesting numerous times when they call me) to pay the money back to me - nothing. Now I noticed on a statement I just received I owe them money. When I logged into the Self-Service Portal, it actually says I owe them R599.38!!! Then going back to March 2020, I noticed they have just put a subscription on my account again without my permission!! This is ***** and THEFT!! I have requested full statements via their ***. NOTHING! I phoned them now and was number 89 in the queue, and assisted 8min later. But couldn't hear the other person, yet they could hear me perfectly. I am beyond appalled at what Multichoice think they can do!!! I told the agent that they better resolve this by end of today, failing which I will go to the SAPS and open a case against Multichoice!!!
