if in my opinion you do not have to worry, because your account is already locked and it's safe, all you have to do is report to admin and hope the admin will respond quickly. because your account can be locked because someone will change your email and you will get verification in email, if it is not you then you will be able to lock your account with email and it is security using email in this forum, so in my opinion your account will be unlocked because it is very strange if you can lock your account for security but admin can not help you to unlock your account, so in my opinion maybe admin will send a link to compose your password in your original email (your email address when you lock your account).
