Did not answer because I did not recognize the number. They left a voice mail in female mechanical voice saying IRS had issued an arrest warrant for me and to call that number asap to stop the warrant. It was all very ominous-sounding. THIS IS A SCAM. THE IRS DOES NOT CALL, THEY SEND LETTERS. I got a similar call from a NY number yesterday and reported it to FTC and NY Attorney General's Office. Don't be a victim.
