I am sorry to hear you are having so much trouble with the credits.
Reading your original post, I remember a dive shop I once worked for had an arrangement with a local private high school for credit for the PADI open water course, and for a bunch of other things (like AWARE classes for science credits and AWARE cleanup dive participation for service hours).
I don't know what the situation is in your town, but did you could try contacting the local dive shops and see if they have similar arrangements with a local high school... if one shop does it for one school, it may be a way to get the headmaster/principle to accept your ACE credits.
If you try this approach, please let me know how it turns out.
