Standard Bank Admin does not care

I Settled my Revolving credit loan in Aug 2021. I asked for an outstanding amount and I paid the amount that was given to me. After the payment, it kept showing an outstanding amount. In Oct Experian was updated and showed an amount as written off. I contacted Standard Bank Personal lending and spoke to Kananelo on 08 Nov 21. He advised that this was incorrect and requested the Admin department to correct it. Since then I have followed up every week with the same answer, no feedback. Last week the consultant escalated the issue but still no result. This has a negative effect on my credit score, and no one seems to care.
