These guys are calling your number and saying if u ignore the number the first time,, and happen to answer it out of curiousity as i usually dont. That they are coming to your house n 5 min. I have reported them to police and having the number traced if this should happen to you please do the same as it was a frightening experience for me , with all the violence that is going on n our country.. U cant be too sure. Safety first !!!!!
