Telkom Debit dept poor service delivery is negatively affecting my life

Telkom Debit dept poor service delivery is negatively affecting my life. During December telkom allocated R1222 incorrectly into my account which resulted in my number being suspended. I paid telkom shops 3 visits without and solution and later opted in contacting Telkom billing dept n was assisted by a guy named Hadebe L who was very arrogant. He admitted to the incompetency which affected me n told me that since it was their mistake i wont be penalized n i mst jst pay R500 as per the contract agreement. But to my surprise telkom debited the total amount of R1 222 on two different dates 19 n 20th Dec instead of only R500 . I called Hadebe to address this matter n He told me to email the proof of documents of which I did up until today I haven't heard from them, they only activated hereafter and deactivated again on the 16th of Jan 2026. I dnt know what to do cos is affecting my credit score negatively. I went to telkom shop again today and also they are as confused as I am. Please help me.
