Who called from 3474786214

Called twice at 6:56 p.m. and 7:11 p.m. First time, no one on the line, so I eventually hung up. Second time, I didn't say anything and some guy eventually got on the line, said "Hello" and hung up.

I also got a call from 3474786214, a number I don't recognize and did not respond.  Life is so unsettling and has been since we left the womb. . . .

GOT 2 CALLS IN A ROW, SOMEONE SAID SOMETHING THE FIRST TIME, NOTHING THE SECOND.  PLEASE SEND OUT THE HOUNDS.
