Who called from 3105393965

caller called twice on october 9, 2007 and never left message. second time hung up as soon as we answered.

I missed a call from this number on October 23,2007, and I tried to call it back using my work number. NOTHING! This is fishy!

called my number i called back and someone hung up twice. then all i got was a busy signal.

I think this caller may have been trying to get identity info from me,
they tried to verify my address and claimed I may have won a prize.
This was not a recording, it was a female person.

Dec.17 this number appeared on my caller ID at 3:52 p.m. with no message. (CA Reading Service)  Another call from this number was at 7:40 p.m. and I answered.    A woman said I was in a drawing for $25,000 or some car and the drawing would be at the end of Dec.  My name and address had be sent in from a bank or credit card company.  She wanted me to verify my address.  She had it right.  I asked her how she got it and she said again, from a bank or credit card company.  I didn't tell her but by the questions I asked her, she may have guessed that was it.  I tried calling the number back and it just rung and rung.
What can I do now if she thinks that is the right address and uses it?
