MTN ***** Account

In the past few weeks I have been requesting for MTN to send me a letter stating that someone from MTN approved a contract **********ly using my ID number. I have been promised by Lindokuhle Gcwensa that this issue would be resolved on the 30 of April 2022, and I have been sending emails and I don`t get any response from him now. My credit score has went down due to this account, and now I can not get a good interest rate due to a low credit score.
