From Jennifer Mulrean at MSN Money:
If you think you've been scammed, you can file a complaint with the FTC and the Internet Fraud Complaint Center. But the most important thing is to notify the bank or credit card issuer of the account that has been compromised. You'll probably want to close the account and open a new one.
If you've given away your Social Security number, you should also notify the big three credit reporting agencies - Experian, Equifax and TransUnion - so that a fraud alert can be placed on your file. That way, if anyone applies for new accounts with your Social Security number, you should be notified at home. You should also start regularly monitoring your credit reports, if you don't already.
