No response.

They're a 3rd-party organization that handles promotions for Verizon Wireless. They offer free phone upgrades and other plan package options that may not be available directly through Verizon. It's not *really* Verizon Wireless (which makes sense as to why the recorded message says "Thank you for _your interest in_ Verizon Wireless" as opposed to "Thank you for _calling_ Verizon Wireless"), but rather they work with them in some capacity.

When I answered they just hung up. Ok thanks for the information about Verizon.
