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.
They (all phone providers) can stop the caller ID spoofing. They just don't want to invest the time and money to do so. It's finally a bipartisan issue but as long as Ajit Pai is the FCC chairman, nothing will happen aside from a few pay to block gambits.
