Breach of contract

I cancelled my month to month contract with them at the beginning of October 2019. They keep billing me. They changed my contract to a more expensive one which was apparently system generated in other words thereto computers are ******* and do things all by themselves. I ordered the new product fir R190 for 50Gb. Long story short Waseem called me on monday to say he has taken ownership of my queries and he will sort out my account and have my new sim for Telkom package delivered pronto. Now my account is inactive I cannot login or track my order. Oh and my rooster was unplugged but still used data.......interesting. consumer council anyone?
