Good morning Christina,
I don't have any contacts, however I just wanted to say that it appear that you're getting all the tough contracts. :) On the front page of this site, there is a search option. As a last option, you may try there. I've actually found it handy a couple of times to find useful advice in a pinch. I wish you well and I'm sure someone will come through!
Ooops!! I meant Groups forum. There's one for GMAC as well. Just an idea........
