Caller asked for "steve".  
i replied i'm steve, who's calling?, and they hung up.
great business model.

Caller hung up

Jerks! They keep calling, I answer, they are gone. You try to call the number and you get that obnoxious "beep beep beep... your call cannot be completed as dialed".  There ARE ways to figure out who it is.  It won't be the first time my attorney stopped an annoying bill collector looking for some dead beat that's not me!

hung up after 2 rings

They identify themselves as "THE CANCER RESEARCH FUND".  There is no such orgaization listed on teh web.  There are of course names that are close to this.  Looks like a scam to me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
