DSTV Ripping Me Off

I have a debit order running with DSTV for a few years now. My normal debit order is R514 which goes off on the 7th of every month. This month my account was debited of R782. I called the call centre on 09 March to query it and was told that I had added another package to my current package which is why my bill was higher. I explained that I did NO such thing, and I was then informed by Malcolm that they would reverse the difference back into my account. I called in again (twice to query the status of the call) as I did not get my money back, they said that the call was with the financial department and I would get a call back soon. I called in again today(23/03/2020) because I received an email stating that the amount could not reversed as I had added DSTV Indian package on 17/01/2020 to my existing package. So I called in to the call centre to query what was going on, I spoke to James Pillay (the supervisor), he was very unprofessional and did not know the difference between a call centre agent and customer???

I cannot understand how they are billing me for services I did not request. and no one knows what is going on.
