Who called from 3199832121

Just got a call less than 5 minutes ago, around 12:15 PM EST. Didn't answer, no message left.

Got a call from dis number n i missed it wanted 2 no who was callin not upset i just want 2 no who was callinh.. so i wldnt miss it again

Who the hell is this and why doesn't somebody put them in prison today?

I just set up a contact  name in my phone called Jack A** Callers, and when ever one of these callers call my phone that I don't know and don't leave a voice mail, I put them into the Jack A** Callers contacts list which is filtered to go straight to my voice mail. I never hear a ring from that phone number again!!!

I get it we all got a call from these people, how do we stop it, does anyone know?
