Transunion Credit Bureau negatively rates for non existent accounts even when they know there is a problem

You gave me a negative credit rating with Telkom but I have had no accounts with them since 2013 and owe them nothing. I walked into the Telkom branch in Sandton City and presented my ID which they scanned and confirmed this. I logged a claim with you on the 17th of December 2020 and you requested an affidavit signed with the police, proof, of address, 3 signatures and a certified copy of ID which were submitted the same day and I have proof. You stated it takes 20 working days which have passed. I contacted your Darian on Wednesday the 13th who could not find record of my dispute and would come back to me but didn't. I called your Sibusiso on Friday the 15th and asked for a manager to call me but received no such call. I called your Dandile on Monday the 18th who put me through to team leader Bongani who gave me his own email address and then finally acknowledged receipt of my documents on the 5th submission, with a full record of my prior submissions attached. Bongani was honest enough to tell me there is a known problem with Telkom submissions to Transunion so why are you then implementing negative ratings freely when you know there is such a problem? This is messing with my life! It is unacceptable behaviour and nothing more than institutional bullying ! I worked within your own rules and parameters for resolution and you have failed me by breaking your own rules. I WANT MY MATTER RESOLVED, THIS IS YOUR DOING SO REVERSE IT AND I AM NOT PREPARED TO WAIT ANY LONGER! THIS IS A PATHETIC ABUSE OF MY RIGHTS!
