Telkom deactivated our data and left the ********** contracts active on my account

I have only two contracts only for data with Telkom. To my surprise my bank account was getting debited for other contracts I have no idea they were existing without my knowledge, meaning they are *****. When I call their agents and explained to them they deactivated the contracts I have been using and left the ********** ones active. I am frustrated because my son and I are studying and we are writing exams.
