MTN - ABSOLUTE joke with customer care

I have been a subscriber since 1995/6. In Oct 2024 someone at MTN loaded another contract to my profile and I was debited with R550odd. I contacted MTN ***** only to be told to contact MTN Cancellations dept!! I have since spoken to countless aimless souls at MTN each as useless as each other. Each month my bank account is debited... I looked at my MTN February statement and a little ray of sunshine in that the *****ulent contract is now no longer appearing on my statement.... I decided to send a mail to *** which is on said statement - only to receive an automated mail back that the mail box is closed - figures... I then send another mail to *** and low and behold I actually get a response from a human... but that human is now telling me that I need to go to a Police Station and get an affidavit in ORDER to get my money refunded. Seriously MTN, after all these months... I advised them to get the contract out and have a look.... secondly if they have now stopped this contract from my billing invoice then why do I have to go to a police station. I have resorted to sharing on FB, Insta, X and of course mates. Someone at MTN just do their job, surely not difficult.
