This number was received as a missed call. I called it back and the line didn't even ring once before a "robot" at the other end terminated the call. I'm just really curious as to who is behind this game of charades.

A call that ID'd as Go Green Recycle shows to be from Atlanta, GA.

Don't answer. If they want to leave a message then a call may be in
order. Otherwise we know what it is.......

Google Maps placement solicitation.  NOT Google Maps.  Rather it is some sleazebag firm acting like them.
