My life is living hell

I took a loan from Fin choice, 3 years ago, i settled the account in 2019, Ever since i have been fighting a huge battle to have the account closed on my credit listing it still shows as open, i tried to log a dispute, the account was closed now it is open, If Fin choice did their job to update the accounts, why were they closed and re opened on note that the account is paid up in full and paid up letter was issued.
