Credit record not updated 7 months after settled accounts

Due to payment default, my Finchoice accounts were handed over to Norman Bissert and associates. I settled the accounts in 2019 and received settlement letters. Both mobimoney and loan account still reflect as outstanding and overdue at all major credit bureau inspite of me sending the settlement letters to their legal department as they claimed to have not received the payment update from the company that I was handed over to. I have called several times even sent screen shots of the credit report along with the settlement letters but the updates are not been done and I get no response on the emails. It looks like writing a bad review is the only way to get a response from Finchoice and this is 7 months after I settled the last account. I understand that the record will be on my profile for 2 years but the account should not still be active with overdue money and installments because it is paid up and closed.
