******** blacklisting

I have a contract with vodacom since 2011, i never had any issues with them until now, for the past 3months i have been checking my credit profile and vodacom has been appearing when I contacted credit bureau i was told I am blacklisted. I contracted vodacom customer care and the lady who assisted me said my account is up to date for 2023 the listing was done back in 2022, she then transferred me to accounts and the guy who assisted me told me the red tape can be removed but it will take 7 to 21days, i asked him why wasn't it done back in 2022 because the first consultant told it was supposed to be updated then, he told me the lady was not supposed to confirm that. Can I request they fix their mess with immediate effect as it is affecting my credit profile negatively i am currently busy with renovations now i have to put my project on hold because someone failed to do their job in 2022, can i be cleared with the credit bureau as my account in up to date it's not in arrears!
