just about everything which could go wrong has been going wrong. Eg even the authorization code to approve the transfer (after paying the ransom demand to "unlock" my domain) doesn't work - in any of the places I was told to enter it.
possibly finally succeeded in authorising the transfer after phoning up to complain and then having to wait for them to send a new transfer authorisation code (which, suspiciously, was nothing like the previous short one they sent).
