Go submit a ticket and stop complaining on forums.
They moved my Premium Enchant Rune for me when it was claimed on a character I was AFK crafting on.
People tend to come on the forums more about these issues or putting out a small PSA.
"submit a ticket" nexon isnt so nice about moving a item to another character if the player logged on to the wrong at the time.
They would promptly say no to a request of that sort. Its better for them to keep tradable within the acc so this doesn't happen again.
