DSTV contract and deactivation

Firstly, payment of R964.00 for my DSTV account went off by debit order on 1st June 2020. Today my DSTV has been deactivated and I have been unsuccessful in reactivating it. Doing it via their dstv.com self help service, it says that my smart card number does not exist. Every phone call I have tried to make to them using my landline and my cellphone, cuts off somewhere within the period I'm waiting for a customer care person to speak to me. Secondly, I bought my DSTV explorer when it was on special at R899 for two years. This was in April 2019. Despite that they are still charging me a higher rate each month; in fact the amount is never the same each month. It's always morebthan the contract rate of R899.00. In the past I have spoken to them on the phone and they say they will fix it and credit me with what is due to me. The last call I made about my contract was on 29 May 2020 REF NUMBER: ***6. I have had enough of their shoddy, uncaring service and need this sorted out immediately. Issue one: unblock my dstv; second issue: stop overcharging me on monthly rates.
