Foreign person answering the phone says he's with tax Investigation, then changed it to the IRS, then finally said it is TAX Crime Investigation.   Very arrogant and wants personal information.  Voice message left on my mail said "if you don't call me back with your lawyer's name - it is on your head!

Just got the same call, informing me of "urgency" and last words, "if I dont hear from you or your attorney on this urgent matter, I can only wish you luck...I call that a threat!!!!

Just got the same call, left the same message. Sounds like a woman robot and says his name is Officer Jason something or other.
