Absa loan division never closes your account even when paid up

In Feb 2024 I paid off a loan I had with ABSA. A confirmation letter or 'paid up' letter was sent attesting that the account will be closed. However, this account still reflects in my credit report as unpaid which is negatively affecting my credit score. I have been in contact with absa loans and complaints department since August 2024, with multiple reference numbers and promises to no avail. Initially I thought the people dont want to help, however iam begining to think its intentional. We have to be slaves to their system. ABSA has no intention of helping anyone. They have been the wall between and purchasing first home loan.
