Update my credit record

I had accounts with Finchoice which were paid up last year February, i have tried one too many times to get the accounts off my credit bereau but i'm not winning. I have lodged a dispute with the credit bereau but my query is still not resolved because Finchoice advised them that i still have an active account, please update my credit profile accordingly, i have a paid up letter for those accounts but i don't understand what else i need to do to get it sorted out.
