Sorry to hear that, that sucks.
Curbed my new 18" Mille Miglia wheel the morning after I put them on

I couldn't believe it. I was used to 16" with the extra outer rubber.
I couldn't repair it as it was powder coated. The damage was minimal, but enough to pi-- me off. Went up on eBay for half what I paid and got a new one within a week.
Hopefully they're not powder coated and painted, so you should be able to repair the damage.
