I feel for you, I really do however, you can't ask for a replacement for damage that in reality, you caused. That's like saying I dropped my phone in the swimming pool because my pocket had a hole in it.
I have to admit it would be nice if you could get something replaced because you scratched it. It'll never happen though.
I hate anything of mine getting scratches in it. I stress out really badly if I ever scratch or damage anything I buy. Sometimes I even lose sleep because I can't stop thinking about how it happened or how to fix it. It's stupid, I know. I just can't help it.
