Who called from 2122903571

got a call from this number, calls and hangs up. It's my cell phone and I think it is National Direct Sales.  Any solutions?  They keep calling me from different numbers. I block one and they call on another.

calls and hangs up several times. No answer when called back even from different number or even private number. yet seems to know my name.

i get a call from that number too!! i didnt pick up though...

I'm having the same issue with this number, calls a couple of times a day and hangs up.  I'm just not picking up anymore. Obviously someone needs a hobby.

Same issue here.  Several calls from that number.  They hangup and don't answer when I call back, even from different numbers.  Help!
