Just got a call from this number--it was a guy with an accent I couldn't place claiming to be from the IRS, that they knew about a letter I had gotten from the IRS (that part was true), that I was being audited, that there was a warrant issued in my name, that I would have to travel to Washington D.C., asked if I thought he was joking, claimed that if I hung up he would have to dispatch a patrol car and have me arrested. At that point I hung up and made myself a sandwich.
As of this writing, an hour later, I am still a free citizen.
Got a call from this number 3 times in a row. The first two sounded like someone butt dialed me, but the third message stated that he was from the IRS and there was a case against me and if I didn't call back they will file a case at my local police department. LOL Seriously?
