As you're probably aware, we don't have active Customer Service support on Alpha/Beta/PTR realms; their main focus is on the live, retail game.
That said, we know that it's really a bummer if your character gets stuck while testing, especially if you've invested a lot of time on them or are halfway through a zone.
So while I can't promise anything, if you post here with your character name, your realm, and a brief description of the problem we'll try to help you out. I can't guarantee we'll be able to fix your problem, nor can I guarantee a rapid response.
