Thanks for all the advice, everyone. Just to clarify, the hubs aren't damaged in any way that would make them unusable. They just have some surface scratches and nicks - I wouldn't want to go to the trouble of sending them back or anything like that. Mostly, I just want the friggin' store to email me back and say, "we're sorry we packed those so badly and we hope it won't stop you from shopping with us in the future." I didn't ask them for a refund or anything, I'm mostly just looking for an apology.
Mostly, I think it's just this strep throat making me cranky.
