Technical Support Forum, as in your client won't start all or you are experiencing errors and glitches. You want Feedback Forum (where they take suggestions).

And to be honest, they are under no obligation to let users who are not paying for a service to use the service. (ex. downloading content they can't play because they aren't paying). Unless there's a free trial involved, I am hard pressed to think of any Pay-to-Play games that allow you to download the game before purchasing it.
