Paid up account

I had a contract which was handed over, I settled the account in December 2019 then the debt collector said they will update vodacom to update it. April it was not updated I then contacted vodacom on the 9th April 2020 they sent me a clearance letter stating it has been paid in full and they will update the bureau in 7 working days. Now it's August and the account still appears on my profile.
