Who called from 7704622105

The caller ID said "Unassigned", so it's a telemarketer/scammer.

Called me on my cell phone saying I was preselected to win a trip.  Said on caller ID from Villa Rica GA

Nerds called today. Scammers

So, the VoIP spoofing scammers have moved on to another block of area code/extensions.  Last month it was 762-585-xxxx.  I guess 770-462-xxxx will be the new ones to add straight to the blocked list.

You'll never know because that's not their actual number - they're spoofing a real phone number using VoIP.
