Scott did you sign a buyer's order or purchase agreement or the like when you ordered the FFE?
Sadly, this type of thing occured also with the Volt. If you don't have a signed agreement then you are at the mercy of the dealer. And if they have more than one person asking for the car they will do what they can to get the highest price.
You might appeal to the Sales Manager to honor the orginial agreement, and after that try the owner.
