Sorry to hear about that
I don't really know much about rescues, but what they did to you was pretty mean. Did they expect you to throw a fit and demand BOTH of the kittens? You were just being reasonable and co-operative. As for your fiance's allergies, I'm curious as to why you still want to adopt kittens? I'm allergic to cats as well, and I could never consider owning one, as I would always have red eyes and be sneezing constantly
