Failure to update my transunion account by deleting a falls, ********** account which was opened with my name back in 2016

Vodacom had failed to update my Transunion account from 2016 till date. I clearly specified to Vodacom that I have never opened an account with them. Sent all requested documents including affidavit. Requested that Vodacom send me a letter head confirming that the ********** account has been closed however till date, nothing has done to resolve my complaint. Transunion still not updated. No Letter Head from Vodacom received confirming that their ********** account opened in my name has been closed. MAY I RECEIVE CONFIRMATION ON A LETTER HEAD FROM VODACOM THAT THE ********** ACCOUNT THAT WAS OPENED IN MY NAME HAS BEEN CLOSED. MAY I PLEASE BE ASSISTED BEFORE CLOSE OF BUSINESS TODAY. IM SICK AND TIRED OF YOU VODACOM.
