What you’re describing doesn’t make much sense: why would a registrar lock your account? Why would a registrar change your domain’s nameservers? If you have direct contact with the CEO then you’re already far ahead of wherever people here can get you.
You said “backup codes” so I’m going to guess what’s actually happened is you lost access to your second factor, your domain has expired and you’re unable to log in to your account to renew it. Does that accurately reflect the situation?
