Account blocked , how to retrieve the password ?

Hope the solution in attached file might help you.

No, as I have already mentioned that I donot have answer to the security question.

The file you provided is useful when you know the answer to the security question.

In that case you can contact your range officer for assistance and unblocking your account.

Agree, contact  the appropriate officer only he can solve this as you have no proof to show that accounts actually belongs to you as all mediums are unaccessible now. 

Thank you everyone.

The problem is resolved.Today I contacted the range office with written signed application for password request to a new e-mail ID.They accepted it and sent the mail to the new email address.After that I created new password and security question.
