Call from a # that had NO hits on Google (ditto for several of the report sites), hid their caller ID (said "Name Unavailable"), & *2* sites flagged it as either faked or coming from from outside the US! Clearly some sort of scam.

Caller ID said "CALL RESEARCH". Some guy on the line asked for my spouse. "I said, "Not available"; the guy then said he was taking a survey on how "registered" voters voted in the PA Primary (as if I'm NOT?). I said "How WE voted isn't YOUR business!" & hung up.

Calling it "Fraud" because the caller hid behind "Name Unavailable" on the caller ID; plus within a minute or 2 of the call coming in, calling back FAILED. Oh and ZERO hits on Google for it, either....

2 hours after the call from 835-216-8743? This one had NO hits on Google (I'm hopefully FIXING that). But guessing it was the same spammer as the earlier call, just working up through "available" #s to spoof....

"Name Unavailable" today. Didn't recognize #; almost nothing on Google. 1 site said it was from Canada; another, just that not a valid US number.... ~2 hours later? Another call (same caller ID). That had a different last digit: 835-216-8748 & NO hits on Google!

No message left. Caller ID just said "HARRISBURG PA". Only 1 hit for the # on Google -- some spurious site with a bunch of fake sounding names listed, which has the domain for Guadeloupe (I checked to see what/where ".gp" was for...).

No message left. Caller ID said "PITTSBURGH PA" (yeah, flush left and flush right on the screen -- that's a red flag right there). Another report site ALREADY had this flagged as being a car warranty scam call when I looked the # up.

Didn't recognize #. Caller ID just said "ARDMORE PA" (yes, with a lot of space in the middle). So picked up and hung up. Only hit on Google was one of those "blogger.com sites with a bunch of fake sounding names they show Google....
