They called me yesterday and left a message. They IRS is going to sue me and I need to call them right away. The recording sounded very convincing. Then I realized that in or for them to be able to "look up my records" they would need me to give them my Social Security number. HA!!!!!
If it had been a legitimate issue I would have been sent something in the mail with some sort of a case or reference number for them to go by.
