Not updated records with credit bureau

I had a personal loan account with Absa which I settled in October 2019. Absa is lazy to update their records with credit bureau cos every time I check my credit record it still shows that I still owe Absa. It is unfortunate and depressing that I cannot even apply for a credit because of the account that I have settled last year. I have attempted to contact Absa to update their records with no success. It is unfair that I have to suffer for the action that I took full responsibility for. Why a loyal client has to suffer like this? This is so pathetic and unprofessional.
