After you get them repaired, stay away from curbs. It's difficult with a new car, especially if it's wider than you're used to. I hit mine for the first time in about 7,000 miles the other day, too.
Can't be fixed by normal detailing measures. You can try to find a rim doctor nearby? But I just keep these … happens sooner or later anyway and consistently with constructions sites with narrow roads, or people using too much road themselves in the mountains with a curb on the side etc.
Looks to be a pretty straightforward repair for a rim refurbisher - they'll polish that out, paint and clearcoat it and you'll never know it happened. The tire doesn't even need to come off the rim. If you're having trouble finding someone to do it, check with a dealer - they use them all the time when cleaning up their used cars for resale.
