HANDOVER STATUS NOT BEING REMOVED EVEN AFTER PAID UP PROOF PROVIDED

I have had a loan at Capitec in 2019, due to unforeseen circumstances this loan could not be paid up in time. This loan was then sold to NIMBLE debt collectors. Shortly after it has been paid up and closed. I have just found out recently that Capitec has still got me in handover status as of 2019 and even being provided proof refer me to nimble to sort this out. NIMBLE has provided the paid-up letter and confirmed the account is closed however Capitec refuses to remove the handover status that is negatively affecting me now for 5 years after the account has been settled. I simply get told to speak to nimble as if they can remove the handover status on Capitec's system. I'm going to be closing my accounts at Capitec after banking with them for 12 years due to this. Extremely poor administration. You are negatively affecting my credit score due to an account that has been paid up and closed 4 and a half years ago. If there is no assistance being provided to resolve this legal action will be taken due to damages done to my credit history unduly.
