Talk to the tire center supervisor to repair the damage and to get the best tire guy under him to remount the tires for you. If he gives you attitude or bullshit, talk to the warehouse manager. If you feel like you're not getting the proper service, call the Member Services and tell them about your woes (it pays to be nice to these people, whereas you can raise hell at the store). Don't be bashful when asking for compensation. They'll usually give you almost 90% of what you ask for, so feel free to exaggerate a bit when you make your complaint. All in all, I think you'll get your wheels repaired without much trouble from them.
