i get a few calls, anyone know who this is?

These numbers annoy the hell out of me you answer and no one is there and if you call back its always says its a non working number wtf they just called me how can it be a non working number

They've been calling me today too and knew my name...what did they say to you?

I got a call today, and no one answered. Then I couldn't call back because it was busy.

Received several calls from this number today.
