ACCOUNT NOT UPDATED

I'm not happy the way Compuscan is dealing with my account status. I logged a dispute for the CTI Financiers account to be updated accordingly, but I see that one minute they remove the account and the next they add it with 6 months arrears. And it's so sad that I provided them with all the necessary information including the paid up letter dated 2019 September. I even requested the credit provider itself to send them the email confirming the closure of the account, and the credit provider did and even cc me on that email.
