Another site says the owner of this number is "Recearch" (spelled this incorrect way) Corp., a "surveyor." I didn't answer, so I don't know for sure what they were after.

BTW, they called at 9:35 in the evening. Legitimate survey calls stop at 9:00 p.m.

Received a call from this number at 8:36 PM today. No name or other info on caller ID. I pressed the 'block now' button on my call blocker, stopped them in mid-call.

Called 6-4-16 at 12:22 p.m. CID showed Denver CO.  No message was left. Another criminal calling who is apparently to stupid to gain legitimate employment.

Called at 7 PM with name being "unavailable," which is totally suspicious.  Number blocked.
