The reason all we can do is refer you to toonslab is because in game staff (and forum staff) do not have the necessary tools to handle these issues. That's all we can really do, I'm sorry.
Also, I still have no idea what goes on about unlinking, all that is handled by global staff I believe.
Generally,
[email protected] deals with issues like email changes (since email changes deal with ALL graal accounts associated with the email), and toonslab handles things such as jail timers looping or false jails, or other issues like that.
