Who called from 7603174895

I also got a call from this number.  They left no message.  When I called back, some recording said the extension was unavailable.  Definitely sounds like another scam call.

Called 8Dec2017@9:16AM PST CID=Unavailable. No message left. Also called 27Oct@5:22PM, 19Oct@5:07PM,12Oct@2:33PM, 5Oct@5:57PM. Never leaves a message so it can't be important. If a call is from Unavailable then so am I.

Want homeowners to answer a few survey questions to help determine home values in your neighborhood,
I declined and blocked the number.

Called 13June2017@7:01PM PDT, CID=Unavailable. Seems they're back at it.

Standard MO.
