That is extremely disturbing. Njalla is the owner-of-record (i.e. nominee) for all domains registered through them, rather than merely the registrar. If they run off with your domain you have significantly fewer options for dealing with it than with any other registrar.
I expected better than "shoot first ask questions later" from them. At least shoot while asking the questions; the owner should've had an explanation for the suspension waiting in their inbox.
