Don't call those 202-area-code numbers; that is the area code of the Washington DC area, and as the number might be spoofed, you could be calling an innocent person, or a politician who will have law enforcement investigate.
A repeating recorded message that went something like this:
"Hi my name is Steve Martin, my number is 613-318-8611 and this is your second attempt to avoid an enforcement action by the Internal Revenue Service. In order to avoid being called before a magistrate or grand jury please call so 613-318-8611 Great Meadows (?) can help you."
Person called informing me the US Treasury required contact in order to avoid enforcement. Seems like a scam. When I tried to call back, received busy signal.
They called with the same message as Allan above. But I called and asked: "are you with the IRS? what is your badge number? "07742" Then I laid into him about how much do I owe, HOW much, "calm down lady" my answer "wait you are going to take me to court and you want me to calm down?": "tell me how much we owe and I will pay you, just tell me an address". He was all in a panic because he didn't know what to do with me? -- so he said he would look up what I owed, then he hung up?
the way to get to them is to call that number all day, which is now 202 600-4531 - just keep calling it and they will stop using that number.
