I traded some gold in a game for a WoW legion US copy. After trading and sending the videos of me sending the gold. The live support woman said brb to get the key. She came back and said they were out of stock. They added me and on skype and said they would have more keys around launch. They have assured me they will get me the key and have apologized several times but I still don't know if they are legit or not. (I should've asked this before trading lol) Thanks!

I wanted to know have any of you guys traded or bought/sold to them and how did it go? Did you have to wait?
