Absolute incompetence, dishonest and disgraceful with empty commitments

Would I have a few contracts with Telkom. Included in them were 2x data contracts. One I was using (payment from my bank account) and the other my partner was using (payment from partner's bank account). A while back already my partner changed bank account so we went to update the banking details on the contract she was using. Part of the process, we did a change of ownership to her name so the one she was using (1x data contract) wound now be on her own name with her bank details...just a moving of account to her name. We were told this (MOVING of account owner) was done.

Since then I started getting increasingly more and more messages/calls/harassments from Telkom; call centers; Telkom partners; debt collectors; and every form of legal body corporate entities stating that I am in arrears and owe Telkom money and need to "immediately" pay them. I've even had notice of summons sent to me and section 129 notices sent to me to force me to pay them.

Turns out they never MOVED the account as requested, but rather created a new contract on my partners details and correctly collecting money from her every month BUT while still leaving the contract that should have been moved (with bank details that does not exist anymore) under my name and ALSO trying to collect for that (now duplicate) contract. This has resulted in them unable to collect funds on the account that they messed up that is linked to non existed bank account. Every month of non-collection accumulates and Telkom tries to collect that from me rather (FAT CHANCE!) In an effort to fix this, Telkom went ahead and cancelled my other contract that I was using (other one of the 2x data contracts)...AGAIN INCORRECTLY

Needless to say I have gone back to Telkom shops to resolve this so many times over the last few months that I have lost count. Every time it's the same story and excuses of they don't know how this happened and don't know what to do. Feedback once was even to come back the next week and state my case again to the next person (when the agent is not on shift) - what complete incompetency. Another solution provided was to rather go home and phone the call center (as if I'm going to waste my airtime and time waiting for a call center line only to be told the same). The one agent that helped me in the beginning when this all happened did log a case for this, but it was just closed. Every time I am just told they will re-open the case, but nothing happens except getting another message of missed collection. Another solution provided was to just pay the amount (that Telkom tried to actually incorrectly and dishonestly collect from my contract while duplicating the account). Not a chance in hell that is happening!! I'm not paying for Telkom's mistake where they duplicated an contract and try to double collect. This while I have spend so much on fuel already driving to the telkom shop every time just to be disappointed!? At the point where I expect a form of compensation for all my time wasted and expenses wastes while still no resolution!! This is also now affecting my credit score negatively. What an absolute DISGRACE!!!
