A Supervisor (called himself Mark Thompson) said he was from the US Treasury claiming that I owed back taxes.  When we called back and asked him to verify my social security number, the call was dropped.

We got a call from this number as well.  They left a message but you could  hear background noise and sounded like a call room.  Needless to say we will not be making a call back to them!  Thanks JR for you post as well.

I got two phone messages - said his same was James Cameron.  He was calling from Legal Affairs of the Department of the US Treasury.  A little threatening.  I am not calling back.  Sounds like a scam.

i also received a call. it was a guy with a strong indian accent saying his name was john marshall from the department of legal affairs. couldnt understand him very well but i believe he said that if i do not call back, i should notify an attorney. ill contact the state attorney generals office. i think anyone receiving a similar call should do the same
