TERRIBLE service

I waited until VOdacom stated that i would be able to cancel my contract that has expired. Which i did. Cancelled my account in December 2020. Every month they still take my money and i cant stop it because then they are going to cut my other accounts as well. But i really think it is time to cancel all my account and make sure that all my family and friends rethink their accounts as well. And worst is I was going to take out FIbre account with them that was my reason for cancelling the other account.
