Didn't recognize this number so I didn't answer. No message left. When I blocked my # and called back, the standard "Welcome to Verizon Wireless. The number you called is no longer in service, has been changed or disconnected. If you feel you have received this recording in error please check the number and dial again." Obviously some kind of scammers spoofing a number to make illegal robo-calls. Now blocked. This is the second time today this has happened, the other number was completely different.
