Unfair billing practices by Multichoice

This company has reactivated my old Decoders which were deactivated by me. When i called i was told it was system automated and they would reverse the funds since June 2024. I have called 3 to 4 times in the past three weeks wherein they activate my account and promised that their finance team would reverse my funds but never did, as a result i get deactivated every second day until I call them again. I am tired of calling them, I have paid them and I need my connection and my refund.
