Unsatisfactory background check?

You have the legal right for a copy of that background check. If Choicepoint is refusing to give it to you, then contact an attorney. According to the Fair Credit Reporting Act (FCRA) neither the bank, nor the background check company can deny you a copy of what they obtained about you. They may not have to tell you why they made the decision, but they absolutely must give you a copy of your background check.
