stuck in the realm shadow

hello it's been 2 days that i'm stuck in realm shadow the death knight quest, i opened a ticket but nobody answer me.
my request is finished I can't cancel it or start again I'm really blocked

I've already tried to unblock my perssonage using all the existing methods.
I can't delete it to start again because I've sent 10K PO on this perssoning

Have you done this in your website control panel:
