Interesting.  Got a call, left no message.  Call back got ring then a click, then a slightly different ring followed by "Hi you've reached Michelle, sorry I can't get to the phone right now, etc."  Sounded like a personal message.  I've been inundated with calls like this lately.  When I do get a live person to respond to my call back, they say they didn't call me.  I suspect the scammers are spoofing randomly.  If you don't recognize the number, don't answer.  This one is forever blocked.
