I received a call from this number at 01:59pm on 03/02/17. There is no caller ID. I called back, and an automated machine stated that the survey they were conducting has now closed, and provided no further information.
Looks like this number is a new one to be used by some variety of crooks. Maybe a bogus survey according to one above report? They called me today at 3:25 pm but were stopped by my blocking service.
