Telkom charges even when services is cut.

I have contacted Telkom a few times regarding my month to month ADSL package that has been cut as I missed two bills. I asked them to please stop billing me so I can bring the arrears up to date. Consultants said they cannot stop as it is in arrears. My service has been cut so I cannot use it. How can you bill a person for something they can not use? Two bills I know I am responsible for as my service was running but the rest makes no sense. And in my opinion its ******** to charge for a service thats not delivered. Call customer service each consultant sings the same song, if you get through, social media team also not much help.
