DO NOT...I REPEAT...DO NOT CLOSE ANY OF YOUR CREDIT CARD ACCOUNTS! The longer you have had them and have paid faithfully on them, the higher your credit FICO score could be as they take this as one MAJOR piece of information for your credit worthiness. Did you apply for this credit card? Does it have a high credit limit? It may or may not hurt you. But if it does, it won't be anything major. Just don't fill out any applications for credit as the lender may look at that card and what the credit limit is and think you will be going on a major shopping spree! Tell the lender what happened.
