I gave the location of the store to the Customer service person directly. Turns out that though labeled Verizon Wireless wireless (not Radio Shack etc), they are indeed a third party -- hence the deception. Yes, I thought mistakenly that a place using Verizon Wireless logos, selling only Verizon products, was a corporate store -- my mistake, I was successfully deceived! They ARE authorized to charge the upgrade fee, however, especially as Premium Retailers. Regardless, they list it on their receipt as an item, and charged zero. Nowhere did it say this would be added to my bill. This is the fraud part.
I realize that the people with "customer" names responding to posts are not actual Verizon employees, but I assume they are freelancers of some sort. At least I hope so, for their sakes.
