BAD BAD BAD BAD

To whom it may concern. I come pleading for help!!. I have received numerus calls from a few collection agencies regarding a MTN account that was cancelled on the 30/01/2020. I have advised them over and over again this was transferred out of my name and sent all the supporting documents. I have sent many many emails with all the proof. Not a single person comes back to me. When I advise via the phone they need to please check their emails I get told “ oh I will escalate this to the relevant department” Between Nimble group, MBD Attorneys and MTN legal they then question me as to who is handling my account?? MTN legal department has contact me 19/02/2021 I too sent them the relevant documents and well as you can tell no word from them either?? Then a few days later I get the very same call, low and behold I get told the same thing???? NOTHING GETS RESOLVED???? I requested a manger call me time and time again and TADA nothing?? I am now on the credit bureau for what reason?????
