Unfair treatment by Finchoice.

I'm very disappointed with Finchoice. When I was applying for a homeloan in October 2019 my consultant advised me that I had an account by Finchoice that was still open and I needed a paid up letter for that. I called finchoice and they advises that they do not offer a paid up letter for that account as it is a carried over account but they will update it with the beaure as closed , three months later the account is still open and I also noted that they so random credit checks without customer consent. I need this account updated accordingly and not to be sent from.pillar to post
