Just got one, don't know who it is because I won't answer unknown callers. However, I live in an area that got hit by hail last week, and am getting inundated with unwanted calls from "roofers" who want to make my life whole again. Do not answer them and would not respond to someone soliciting work on the phone especially from out of state -- only deal with word of mouth from people in my town whose opinion I respect.
Caller ID indicate Unknown Call. Did not answer and no message was left. Will not answer unwanted calls, unknown callers, or out of Sate calls if I do not recognize the #. I continually report these invasions of my privacy as I do have an unlisted number and have registered with the DNC. Doesn't seem to be doing any good. Another Government Program that doesn't follow up, but costs, We The People....Sad
