Comes uo as unknown. I would like to know who it is.

This phone keeps appearing on my caller ID as "unknown". It is annoying!
(Maybe we should contact this unknown person, but I can not get a first name.
I keep looking at the white pages for unknown and there is nothing.) LOL

He asked to do a 20 sec survey for free $25 gift certificate to target. I asked 3X in the course of this if he represented a sales co.  He said the same thing over and over about the co. name, implying it was a utility.  Then he said at the end I had a CHANCE to win the gift card and and a "free" water test.  This is a sales pitch to sell a water system. Don't fall for it.
