I received a message from someone on both my home and work voice mail.  The woman on the phone acted as though she knew me and called me by a nick name that I don't use.  She said, "hey, we're in town... we're staying at the (??? hotel) - call me... where can we get a decent meal in this town?"  Never said her name and I didn't recognize the voice.  In fact, she left no name for either call.  I'm concerned this is a very sofisticated scam, as I don't use the nickname she used and no one calls me and leaves cryptic information on voice mail in an unrecognizable voice (unless they don't want a return call).
