I'm so sorry your going through this. I remember reading your story awhile back. Even though I know sometimes things happen in and instant some people organizations stick together in their beliefs. I think its time for you to move on, and agree there are many good dogs in shelters that would love to have a good home. Not all german shepherds go to rescues. My gsd if I hadn't taken him in was going to go to a shelter as a puppy.
