Johnny, make sure you didn't just fall for a Phishing attack.
Change your email account passwords immediately and if you use a common password on other accounts change those too. If you provided any other information like social security number, credit card number, bank account number. Notify the banks/social security/and the 3 credit reporting agencies immediately. (Immediatley means tonight, not tomorrow. You could have 5 new credit accounts opened by morning in your name.)
Equifax: 1-800-525-6285
Experian (formerly TRW): 1-888-397-3742
TransUnion : 1-800-680-7289
Social Security Administration (fraud line) 1-800-269-0271
If you still have them post the links the email directed you to here. You can usually tell if it is a fake link. We can help determine if you just messed up.
NEVER click a link in an email and then fill in personal information!
Go to the site you believe is making the offer directly and follow the instructions there. Any legitimate offer will show up on your normal site. The email scams are a major identity theft issue these days.
PS The reason to notify the credit bureaus and social security is that you can have them contact you by phone for authorization if anyone tries to make inquiries or setup accounts using the info you provided.
