How do I eliminate open accounts that appear twice on credit reports?

alison a asked:


I just pulled credit for a client, and one of his revolving accounts with bank of america showed up twice on his credit report. It’s definitely the same account, I have asked the client about it. It shows up once with a four digit account number, and the second time, directly below with the same balance and payment, and a twelve digit account number. How much could something like this bring down his score, and how do I get rid of it?
