Information not updated at the credit bureau

Took a loan with ABSA a few years ago. Paid it off in august and was provided with a settlement letter and confirmation on email that my account has been paid up and settled and they balanced adjusted the account to nil, therefore the information would be adjusted automatically by the bureau. Realised that to this day it still sitting on my credit record as an unpaid loan. This is adversely affecting my credit and I have emailed Daphne Le Grange (who was really helpful at first) to inform the credit bureau to update my information however it's been now 4 days without getting any kind of feedback or acknowledgement of my email
