Same call from 720-372-1616 about every other day or so, always a hang up. I called back the number back just now and it's Graven Austin Drake, pressed 1 to put our number on their no call list. http://www.gad-inc.com/
These are all nuisance telemarketer calls originating from GAD. They have no courtesy for calling at bad times. Should be reported top government authorities.
