***** - being charged monthly for something we did not request! Cancel this now!!

Hi MTN South Africa someone in your admin team has added a cell phone to my fathers account ( he has dementia, and is in a dementia care home and cannot deal with this himself, so I am trying to assist my mother with this issue) and we are now being charged monthly for this phone bill. We have not requested this new phone number, in fact, we cancelled his mobile contract ( reference number ***) months ago and recently started receiving charges for a phone that has magically been added onto his account ( by one of your admin team) and now are being charged over R1k a month for phone number ( ***) which we have not requested. We have logged this as ***** and are still being charged monthly. Your team keep requesting that the account holder needs to speak to them, however as mentioned, my father has dementia and is in a care home and has no recollection of what is really going on. We have taken my father in his current state to a shop to have this cancelled and we are still being given the run around and are being charged monthly for a *****ulent phone that was never requested by anyone, especially not my father who is in a care home with dementia and has been for almost two years now which we can provide documentation to prove as such. Cancel the phone account now!
