Got the same robo call yesterday at 2:16 PM and reported it to the FCC as an unwanted call and a fraud about the IRS payment. IRS does not work that way and everyone should file a complaint about this number or anyone with the same message.
Received a "cheap" computerized recording(female voice) from this number stating final warning regarding back taxes. Call this number to speak to a Federal Agent in order to avoid appearing before a magistrate.
