You bought the phone at full price? Did you use the Verizon Device Payment Plan?

If you did not use any of the above options there was no bait and switch. You lose unlimited when you take a subsidized phone. The iPhones can cost up to $850 did you pay $850?

If not you were consumer unaware and you have 14 days inclusive of the day of purchase to return everything and pay a $35 restocking fee per device.

However that unlimited data may not be so easy to get back.

You may have to go to a small claims or superior court with a single right of action to compel Verizon wireless to give it back.

Good Luck
