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.
My husband and I both received calls from this number at approximately 2AM with the same Verizon $100 promotional offer. I called it back and their message is garbled - it sounded like a call that was breaking up.
Received phone call at 1:13 AM. Didn't pick up. Listened to voicemail. Said to go to verizonsummer.com. log on to redeem $100. "at Verizon, we care about you. Thank you. Have a nice day." I called number back from my landline. Call was garbled and broken up.
Obviously a scam. Bunch of douch bags.
