Got several calls from this number over a period of 3 days. At least 4 a day- stating the same thing about owing the IRS money and a lawsuit has been filed against me, blah, blah blah. So clearly a scam.
I finally answered after getting about 6 vm, and told the guy to send the police to arrest me as I could use the break from work and kids. A few days in jail sounds really good to me. Weird, but the police never showed up and they quit calling. LOL
