I got a call from this number. I did not pick up, as I did not know the number. They left me a message that it was absolutely urgent that I call them back. I did not bother, as it seemed like a crank call. I then checked the number and saw all of your comments. I will NOT be calling back!!!
"IRS is filing lawsuit against you". Call the number they give and you get connected to india call center. I received these exact same messages last year and now it started again.
