Message says "Hello. This call is officially your final notice from IRS, Internal Revenue Service. The reason of this call is to inform you that IRS is filing lawsuit against you. To get more information about this case file, please call immediately on our department number,202-470-0729. I repeat. 202-470-0729. Thank you." I also received the exact same message (but with a different phone # 202-738-1919
). When I immediately called this number back, a man answered "IRS". I hung up.
