calls at all hours doesn't leave message.  The first call I received was during a soccer game on Saturday aorund noon, I didn't answer because I didn't recognize the number.  They called again at 9pm last night.  I know it's from Michigan, caller ID says that.  I don't have any outstanding bills.  I have no idea how they got my number.  Brother tried to call the number back from another phone to see whom it was and couldn't get an answer.
