Still not working character rename throuhg e-mail

Hi. i’m a player on an Asia server

after ladder reset
asia server can’t change character name through e-mail.
i removed character name and tried to change removed name , but email said A character with the name ********* already exists. [Click here to retry]
. but still i can create removed character name in game.
Of course the character I tried to change was in a different account

even i await deleted character name 7 days, but still removed character name can’t change. . :cry:

Plz Fix it
