Something else you might consider should you push the issue:
Do you really want to go to a school where they view you as having forced your way in? And, do you think things will go any better once you get there?
I know an acceptance, any acceptance, is what we all live for but at what cost? I was declined in a previous cycle and contacted them to see what I could do to strengthen my application. The reply was, "Frankly, we are looking for applicants who can contribute to the field of dentistry longer than you will be able to." (BTW, I am a 40ish non-trad.) Needless to say, I had an age discrimination suit, and possible acceptance, if I pushed the discrimination issue but I decided it wasn't worth attending a school where the feelings from both sides were so bad. Now granted your situation is a bit different but it has the same undertone. Good luck in deciding how far to persue this.
