I used a grail to boost my Lvl 193 knight to Lvl 194, but now I cannot use him. Or my level 30, or my level 24 knight. I don't know why. I have written to customer service 3+ times over the last few weeks to no response. I tried refreshing etc as well.

I'm at my wits end because that was my highest level knight and I used all my items on him and now he's stuck in limbo, and I can't get even the simplest customer service response. Is there a customer service rep here that can help me? Or
Even another player please? I've been playing for well over two years
