My account has been disabled for security reasons, it says but I can't receive email to reset my account unless I can't login to iCloud!

My iCloud account has been locked and I tried to reset it but unless I have access to iCloud account, I cannot receive email to reset the account! Anyone knows how to reset the account? I asked for the phone support but it didn't recognize 'iCloud' as product!! Infuriating! I can't use my computer! Can anyone help me?
