It is the applicant's responsibility to forward the completed form, not the Examiner's!
The signature in your licence on the Ratings - Certificate of Revalidation page is the one which matters - the form sent to the flunkies at the Belgrano is merely for them to keep their records up to date if they can find the time...
But any reputable Examiner should explain to you precisely what's required and what has to be signed etc. Why didn't yours?
