We do not recommend deleting of accounts since once the account is deleted, you won't be able to create new character file on the same server anymore. We highly suggest creating a new character using the same account instead of deleting it if you are seeking to roll back your progress.
If you still wishing to skip the 7 days of cooling down period and delete the account right away, please submit a ticket to our Customer Service Team.
We are glad that we can help you solve the problem
