Unfairly account handed over and now affecting my credit profile

Hi, I hope this email finds you well. I had car finance with you guys two years ago and it was settled however how that account was handled is affecting my credit history. Background details: my car was a write-off and the insurance did not pay I had to do arrangements to settle the balance with you which I did however, that account appeared as behind payment and it was taken over because of that status. Now, given that the account has been settled, could you please clear my name ASAP because now trying to get new car finance or any type of credit is hugely affecting my application. my ID#, your assistance will be highly appreciated.
