I got a call from this number at my parents place.  My mother told me that the man on the other line demanded to talk to me. He refered me to me by my nickname.  He also told my mother, "he's your son and you don't know where he is?"  As my mother is smart and would not give any information out to this person.

Received a call and they just on the line listening....weird!

numerous calls, no one there.
