******* consumer practices

I had a 36 month contract with MTN from 2020 ending May 2023, According to my knowledge the contract was for 3years and after that it would be cancelled, to my surprise it was not cancelled cos apparently I am supposed to call and have it cancelled which is bull**** and now I am being told it has been moved to month to month without my knowledge or consent which is ******* I cannot be forced to pay for a month to month contract that I did not sign up for fix this now I will not pay and you will pay for bank charges
