28 Days after loan settlement still not closed.

Loan settled on 2 December 2025, and yet its still on my banking profile with a 1.74 Credit after settlement. I received a paid up letter, but this loan is still not closed 4 weeks after its paid up, as requested when i requested the paid up letter. Call centre is impossible, and now again a settlement of over R200. 7days after my initial complaint still this loan is not closed. I have a paid up letter for it, how difficult can it be to close something that is paid up? It seems you are charging "insurance policy fees on this loan for a settled loan with a zero balance that was infact in a CREDIT for this entire month if this is not unresolved in the next two days i will escelate this ********* conduct to the NCR.
