Can't delete because of this notification

Hello everyone.
I want to delete my char from Blackrock, but when I press 'delete' I get this notification: - This character is an Arena Captain and cannot be deleted until the rank is not transfered to another character.
This is what it looks like when doing it:

I mention that I am not in any 2v2/3v3/5v5 arena team. I tried /teamdisband 2v2 /tquit 2v2 for an eventual minor bug or something, still the problem persists. I even tried faction change because when you do that you lose all the arena teams and progress. I created a new 2v2 team just to quit it agan maybe would'v work, but no changes.
Anyone has any suggestion? Or maybe a GM to delete it for me?
Thanks!

Maybe create arena teams and disband them afterwards? If not open an in-game ticket
