Caller ID: 202-790-4390 Automated voice said IRS was going to sue me and I should call the number to find out about it. They called at 6:48 AM on February 11, 2016 and again at 8:23 AM the same day.My adult son lives in my home also, so I don’t know if it was directed at him or me. He is 29, and shares my phone number. Also not a student. When the automated voice paused where it would insert a name, it came back with "you" instead of a specific name.
