I got a call from them twice, both leaving an automated message that I was being sued as well... Tried calling the IRS to talk to them about this phone call, but it is to late for them to answer with a real person.
I have gotten several calls supposedly the IRS. This number was left on a message. The numbers showing on the phone are different numbers. I didn't think the IRS called people. Anyway, I have not called it, thought I'd just check and see. It is pretty bold of whoever it is.
