Almond:
Having been involved (as an elder) with cases like this, and appeals to cases like this, I can mention a couple of things. (Although, I will mention that there are some details in your post that are not quite clear to me):
If you married a DFed person, you will be DFed yourself. Even if the marriage is legit, your action is seen as a concrete decision to go against the DF arrangement. From my experience, this is an automatic decision from the Society's viewpoint. They won't accept any appeal. You can get reinstated sometime later, a year, maybe several years. But not right away. You sinned against the Society. The worst sin of all.
If you got married again before you were divorced, this is considered an adulterous marriage. And again, DFing is as automatic as it gets. You can appeal, but the appeal committee will turn you down. The logic is that a marriage is permanent and serious. It requires that you do your homework before you sign the papers. In cases of writing a 'pledge of faithfulness,' the Society wants you to get the OK from your elders first. I doubt that the elders' not having informed you first will work, especially if the 'pledge of faithfulness' material was already in print in the WT. JGNAT is right, the WT wants you to get your elders approval first in any areas where there is a question.
