Telkom ******** clients

I have been very patient with telkom but now I've lost it. On the 19th of October I received a call from a Lesedi Lekabe about increase my data on my 1.5 free me bundle to a 3gb free me bundle just for an extra R50. I told her I was interested as long as it was not a new contract and she assured me it was not a new contract on an upgrade just an add on. Fast forward to the 15th of November telkom debits only R388 from my bank but my standard contract I was paying R644. I gt worried cause I didn't want to be paying extra the following month other than what we had agreed on. I called after I gt a message saying I'm nearing my credit limit and after my account was suspended. I called and couldn't receive any positive feedback. I spoke to a Sthembile Shabangu after being given the run around. She had no idea what was happening and told me that I had to pay money to resume my services on my telkom then she told me Lesedi had canceled my account and I'd have to pay an amount of R2500 to settle the remainder of the contract that was canceled I asked to be migrated back to my old contract because I had not agreed to a new contract and she told me it would take 72 hours to resolve. The reference number was ***5.i got a message that it was resolved a few days later. On the 3rd of December I received the same message again and my account was suspended yet again. I called again and after being given the run around I managed to talk to a lady by the name of Dineo Sello she explained what had happened and said she would log a call with technical to reverse this new contract and put me back on my old contract. She told me it would take 72 working hours to resolve the issue and told me to expect some kind of feedback in about 3 weeks. She told me I had to pay R199.99 to get my services working again. The reference number I received was ***7. I asked if I can pay that money on the 15th and she said it would be ok but I will only be able to use my phone and router after I had paid. She was friendly and trues her best to make me understand what was going on. Then yesterday the 10th of December I receid an sms stating that R2532. 99 was going to be debited from my account on the 15th of December 2021. I called them once again and I gt a lady by the name of Basetsana Mankisane who told me that unfortunately I will have to wait for the call logged to be resolved it will be resolved in a few days. I told her I did not make any agreements on settling my account. She said there was nothing she could do I must just sit and wait and hope it will be resolved before the 15th. I feel that telkom is taking advantage of me and I feel I am being ignored and being taken for a ride. I would really appreciate some feedback cause I refuse to be paying R2532.99 when I had not agreed to it.
