Do yourself a favor, go after the source of the provider of this number. It's either a "network", communications network or "manager" They are the ones that sell, share or rent our info. It's the provider that we need to go after since FTC has failed to do that. Be an active consumer that goes after the source. The FTC is too "overwhelmed."
Robocall from a Denver-looking number, something about 'winning' a trip to the Bahamas, and something about a survey. Received this to a cell phone on do-not-call list, I do not do business with these people, nor will I do business with anyone who does robocall. Hung up, and immediately filed a complaint with the FCC: www.fcc.gov complaints
Calling them back gets an automated menu driven phone session that sounds a lot like a real Verizon support line for activating phones. It offers a way to activate your via with a credit card - very suspicious there. This seems like a well played scam. The interactive menus work and offer a way to enter your phone number with a response saying the number can't be found. I didn't try a real verizon number.
I'd be suspicious about answering calls from this number. If you want verizon call their official 800 number.
