I answered the phone and the person on the other end, who sound like a teenager popping her chewing gum, asked for a person in my home by his first name.  When I said he wasn't here, she hung up on me.  When I redialed the number to see who this was, the number never even rang on the other end.  The line was just dead.  Has anyone had a call from this number before?  Would like to know who they are.
