Same as above. Call threatens prosecution. First of all, the IRS and other government agencies do not call and threaten arrest if the recipient (whom they don't and can't identify-clue#1) doesn't respond. Secondly, first contact regarding a court action would be in writing. I would imagine that if a person is due to appear in court, a subpoena would be issued in person. This scam needs to be stopped. The offending phone number(s) should be traced to point of origin. (It can be done.) If out of the country, surely with all of our present technology, there must be methods to combat this at the source to protect American and Canadian citizens from these bogus, hateful, and potentially harmful threats.
absolutely a scary scam. couple of clues: "Magistrate Judge" is not an American term, judgement against you is not IRS terminology; IRS does not phone people.
