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....

Caller ID just said "Name Unavailable" (always suspicious!) so I picked up & immediately hung up. Another site like this one said the # wasn't valid (!) or was coming from outside the US. Don't know ANYONE overseas who'd be calling me.... So , guessing spam....
