What you are saying is that the after you clicked on the lock account link, you never got access to your account ever again?
No, locking the account is just a preventive measure, this way you will be sure the hacker will be unable to use this account for frodulent activities (scamming other users, posting links to phishing websites/malwares...)You can recover your account by proving it is yours. You can read more about how to do that here: Recovering hacked accounts or accounts with lost passwords
You have to be patient though
