If the registrar is different than the hosting company, there should be nothing that the hosting comapny can do.

For instance, if it's registered at GoDaddy, you should have total control over locking/unlocking domain, changing nameservers, contact info, etc.

Even if the hosting company is the registrar as well, you should still have access to a control panel to manage your domain(s).

How exactly are they holding hostage? Is it registered through the hosting company as well?
