Incorrect billing not fixed or attended

I’ve had a billing issue here for the past 2 months!!!! I’ve called into their call center so many times only to be told to keep logging queries that never get resolved. If anyone wants to have a constant headache take a telkom contract. Even worse now I want to cancel this contract because of this billing issue I’m being told I have to wait 21 days till they can tell me how much is left on my balance so I can finally cut ties with them. Telkom sort out your billing issues and how you respond/react to customers.
