Call 1-800-829-1040. This is IRS phone number deginated for the same purpose. They will ask some of your personal info just to verify that you are the person clling for pin and AGI number, after verification they will solve your problem. Dont worry it will not harm your return and will not effect anything and you will not be in any trouble.

Dial 1-800-829-1040 and choose option 2 then after that option 3.

The  reason I knew that, coz I did it few weeks ago.

Peace
