Bad service and retaliatory behavior

I had taken a loan with Finchoice. After months of silence, they (through their lawyers , Norton Lambrianos Attorneys),informed me that i had skipped a payment and the account had accumulated interest. Amidst hearing this information, i proceeded to pay the account through their lawyers on the 23th of August, a value of R400+-. After received8nag a paid up letter from the attorneys, they refuse to update my profile to clear this debt at the credit union. I have been calling Norton Lambrianos attorneys and Finchoice from the 29th till today (15 October 2024) and they either give promises to email the credit beureu or not answer my calls. Till today i am stuck with this account appearing on my credit report even though the account is paid up. I went as far as clearing my report with transition and now i am told i need to register a dispute with experian and wait another 21 day to settle thus matter with experian too.
