I believe that they should eventually get the package, unfortunately the 'parcel post' system has a standard of 'snail' all to themselves (I am assuming not Fedex, etc.). The process is heavy duty unwieldy. Not bothering to list all the steps, but it could take 6-8 weeks.
Although I've been going there forever and know all the DMs/instructors, the name Jaffrey does not ring a bell. I know them by first names or 'nicknames' (maybe Jaffrey is a surname?). Is he the one with the flip up fins, looking like a hockey goal keeper? If so, I know him as James.
Anyhow, I would suggest that you write two regular letters (7-14 days delivery) stating what you had done. I would send them both to Norman (my choice). One to his personal address and the other c/o Watersports Dept., Beaches Negril, etc.etc. On the envelope to the one for Beaches write 'Personal'. Just to let them know to expect the package.
If all else fails, I could try a local call for you, just let me know.
As to the kid sent home - Ouch! I think, however, that the chinese telegraph got to that story, LOL
Btw, I truly think what you did was excellent.
