I got an call on my Verizon phone. It showed up as Verizon on the caller ID. The guy said there was a problem with my payment but I was busy and said I'd call back later. When I called that number back later they didn't know what I was calling about. I said "you called me" and they said "oh that's a scam, we never call you. If we call don't pick up"

If Verizon can't stop people from spoofing their own customer support number on their own network, we're all screwed.
