I see what Peter's point is with regard to the way the complaint form is drafted - what he could do to put the ball in PADI's court is to make and submit a written, signed and notarized sworn affidavit of the facts as he knows them - he saw the certificate and he believes the shop and master and 'instructor' are so and so, and he can provide the student's name so that PADI can investigate it. It is scary that happened.
