Telkom contract

Contract experience with Telkom SA Callcentre. I have had a contract with telkom and I have been ****med by their call centre. My contract was cancelled by their call centre sales agent, I have to be liable for the device amount of R8000. the agent duped me by saying I will be upgraded to Flex on 8 from Flex on 6 with a additional amount of R65 a month on my remaining contract never knowing that she was cancelling my contract and making it paid up which resulted on me being liable for that R8000 at the end of the month of May 2025. I came to know about this when I walked in the store today to buy a sim card. I was told that I have reached my limit and I cannot get a sim card and upon asking the why had I reached my limit with them, i was then told that I have paid my contract. I have been dealing with Cornubia store for the very long time and our relationship with the store is quite good. The consultant at the store told me that i am not the first person to have this issue probably the fifth person. from the time I left the store I have been on the phone with their so called agents for longer than 2 hours. When i requested for the recording of that particular day the simple answer was go to high court and get an order and that when they will be able to assist me with the recording. what kind of bullying is this. I have informed them that this will be taken further no matter what the settlement is
