Kind of sad that Verizon can't block the calls from 800-888-9595 (or any calls with that as the caller id) - this is the scam robocall that claims that Verizon has awarded you a prize of $400 or more.
Verizon is happy to charge your minutes for these unwanted and illegal calls. Kind of makes you wonder if Verizon is getting a cut of the scam profits on the side beyond the charges to their customers.
