Who called from 2143067593

This is a number for an attorney in the Dallas area.  Hangs up when answered.

Hangs up when asked who they are.

I answered a call from this lunatic and he threatened to "hack my xbox account". I don't have an xbox. Apparently he's an attorney from dallas.

Always call in, but no answer when I picked up phone.

Hangs up or threatens scary things when asked who they are. Reported to police as threats were pretty nasty, don't even know why they are calling.
