Got a simliar call today.  Same phone number (caller id stated Butte Montana).  When I returned a call to the same number, it said it was no longer in service.  Obviously a scam.  Same scenario, as previously stated in the above post.  Wanted to know if I was married, or had a significant other.  I stated I was single, and the caller stated they could be here at my address tomorrow and gave me several times to choose from so they could  "deliver" my prizes I had won.  At that statement, I told her to give the prizes to someone else, and I hung up.  I will no longer give any info over the phone, even something as innocent as to confirm my address which they give me.    Just Hang up.  Obviously these scammers have a telephone number routing system that prevents one from knowing exactly who is calling so they can continue their scam without getting caught.  Don't fall for it.
