Contact them anyway. Since your N7 still starts up, etc, they should be able to have you look up reference numbers, etc. At the very least, they can look up your history of when they replaced it before. I can't see where anyone but Asus is going to be able to help you.
I'm also curious how the poetic case damaged your N7? I can't see it doing anything more than slight scratches, assuming it's the case I'm thinking of.
