Downgraded package to DSTV Compact plus but charged for DSTV Premium.

So in Feb 2021 I decided to downgrade my subscription from Premium to Compact plus because of being on Netflix, Prime video and Showmax and really not needing the full package in my house. On my transaction history in March the DSTV App showed that I was charged for compact plus and the amount due was paid. On the 25th of April my account is now miraculously back on DSTV Premium even though I never upgraded it. Spoke to DSTV call centre agent on the 27th of April and he kept telling me that I recently upgraded my account even though this never happened. Channel 101 M-NET is STILL not active on my account and yet you people want me to pay for services I never received or don't want. Your call centre agent managed to change my package back to compact plus but he couldn't do anything about the amount due. Can someone please revise my statement for April 2021 (Compact plus) or I will walk away like many of your previous customers.
