Vodacom not clearing my name after settlement

My ID is *** For *** My Contact nr: *** I Have an account with Vodacom which was outstanding, because I lost my Job after Vehicle accident, after suffering brain-damage/Insomnia I am still recovering I started settling my account with Vodacom, 2 Months into Paying off the account they handed me over ( 4 years later) I didn't even know I was handed over and continued to settle the account with Vodacom the account was settled on 03 January 2023 (R3437) still my account shows under legal and has not been removed from the Credit Bureau, I Phoned Experion and stated that my account has been settled, they in return stated they have not received any updates from Vodacom.

When I try to phone in Since Last week their system stated "the ID you have entered is Invalid how can my ID all of a sudden be INVALID Kindly rectify. The account was dormant for 4 years and was updated @ the credit Bureau It shows I have not paid the account from Sep 22 they made my credit look bad that I was not paying from sept 2022 witch is untrue as I was paying R500 a month. Rectify @ the credit Bureau Please.
