Call and leave no message.  I do not answer, since I don't know the number.  This has happened a couple of times now.

This number called my cell phone. When I called it back from my house phone I got a recording saying that this number is not in service.

Called and asked for basic info. on me like my age, whether I was married and whether I was  employed. They never asked for my birthdate or SS#. The Chinese accent calling from supposedly the US Treasury and then a "917" number and the US government giving me $9 k for being a good citizen told me that this was a scam. They said that I could collect the money at any Western Union, but they wanted me to go to a Walmart for "further instructions to be given to me in the parking lot on my phone and then I would fill out a form there to avoid my state claiming State taxes". I have a Masters in Acct and one reports monies received or earned. There is no state form needed for money wired to a person by any entity. I would have to declare that myself or define that grant as being non-taxable, which in itself sounded implausible. Other posters have said that they want $250 for the tax or fee to be sent to them once they got to Walmart. Of course you will never see the $9 k.

Several calls from this number... picked up the third and heard the phone ringing on the other end and then a pick up of what sounded like, as another described, a boiler room call center and I hung up.

Called twice yesterday. First caller asked my name; I asked to whom she would like to speak, and she hung up. Second person asked for a person and when I said this was not she, he asked me to prove it. Yeah, no. Don't bother trying to call - no answer.
