Repaired keyboard returned damaged

I had a key stop working on my macbook so I took it in to an apple store. The store sent it off on a Sunday and I just got it back today (10 days). They replaced the keyboard but I have noticed two things. The spacebar came back with some scratches and the X key has a gouge on the side that lets backlight through.

My question is what should I do about it?

- This is expected, maybe apple uses refurbished parts

- I'm over reacting, live with it and be glad that apple fixed my keyboard

- Somehow get apple to log this to my account in case these damaged areas get worse

- Demand that apple fix it again (and going without my laptop for another 10 days)
