No feedback and no communication from Defy

We bought a new fridge and we were advised to log onto the Defy page, and register our fridge for the additional warranty. We have been trying this, non stop, and our fridge simply does not appear on Defy's site. I have sent Defy x4 emails, they responded the email #3 and a utter useless and pointless reply. The reply came from a Defy employee who is utterly clueless and who did not even read our email query correctly. Please be aware of the extra warranty Defy offers when considering their items against another brand. Defy is lying and will not assist and support you.
