WoW Legion EU Prepurchase for WoW Legion NA Prepurchase

[Gawerty]

Simply put, I purchased a cd-key thinking it was a 'global-region' cd-key due to a website assuring as such, when I went to use it, it wouldn't work due to my having a NA account and it being a EU CD Key, I can provide the necessary proofs you would want to assure you that I have not redeemed the key, and I am willing to use a Middle-Man, I just want to be able to play Legion and I don't quite have the type of cash needed to purchase ANOTHER key, so perhaps someone would be willing to trade?
