Just got a call from the same number. The message I received told me to log onto verizonthankyou.com for a $100 towards my next phone bill. I checked it out and as much as I could tell the page was a mirror image of the actual verizon website. The difference was in the log in menu, which looked similar to Verizon's site, but asked for more info. The links on this fake page seem to send you to the real Verizon page from what I could tell.
Dwfinitely talk to Verizon and how them this page right here. It's pretty ridiculous that something like this can exist, so maybe if you show Verizon they will be more likely to stop the person(s) phishing us all.
