This is someone who Verizon. They use peoples personal cell phones so you won't  know it's them. You may have
paid your bill already it doesn't matter. the person is sat down at a computer and calls every number that comes up. We have gotten calls from  Calf. AZ. UT. its different each time. Once in a while it comes from a number listed
as Verizon on the caller ID. So the way I do it is if you don't recognize the number or sometimes it gives a persons
name. Don't answer it. I think it would be dangerous for the person who owns the phone. You just gave your phone number out to a couple thousand people....
