Left unintelligible, garbled message on my machine by idiot with an accent. Said something about being the IRS and that they would arrest me! ( they have no grounds) Number is now blocked!
Left a message. What I could hear in an Asian accent of some kind: "your name regarding tax fraud. So before this matter go to the federal claims courthouse, or before you get arrested, kindly call us back on our number as soon as possible. Our number is 386-675-4974. I repeat, 386-675-4974. Thank you and have nice day."
The accent and poor grammar alone mark it as a scam. The number is being blocked.
