Extremely Frustrated Telkom Customer

I had taken out a mobile contract with Telkom in November 2017. At that point of time I had asked the rep to assist me (as I didn't know how to do it on my own) in capping my contract to R1.00 as i did not want it to go on a open line. This was done in the store and the rep had shown me proof that this was done. For an entire year up until last month i had no issues with my contract. It was a fixed bill of (R370.00) that came through every month. Last month i received a bill for more than what I usually pay (R860.00) which was debited from my account. I had contacted the call center immediately to look into this. A case was opened and i did not hear back for 2 weeks. I went into the customer service store in Liberty Midlands Mall (PMB) which no one could assist me either. They kept on saying that they have to wait for feedback from their billing team. I had called back 3 days later and spoke to 3 different people who could not assist either, then spoke to a supervisor (Cliffard) who said he will look into it and provide feedback. He has contacted back saying that Telkom is stating that I am liable for all fees. Telkom cannot tell me how my account became uncapped. I have asked for proof to be sent to me and till date this has not come through. The agents at the store cannot assist with this either. The billing team cant tell me how this became uncapped either after an entire year. I have now received another bill for the end of November for another (R830) whenever you ask to speak to someone in charge at the billing team , they inform you that they cannot put you through. What customer service is this? I think their service is pathetic. They haven't had an issue debiting my account every month and I never defaulted in payments, and yet they cannot assist me with information/help when I need it. They do not want to credit or refund me for the access funds that have been debited. The level of service is appalling. I will never recommend Telkom to anyone.
