Telkom mobile does not know what they are doing (**** Service)

In June 2017 ***** occurred on my account. I reported & provided the necessary documents. After following up so many times I was informed the case has been resolved. They are still billing me the incorrect amounts and they have suspended my accounts even after they debited my account. When I call and enquire a case is logged and no feed provided at times I can not be assisted as they offline. I want nothing to do with Telkom and if you going to take a contract with them expect the worst customer service.
