Chippys on to it, I had the rear wheel of my patrol depart company the day after a suspension upgrade, at the time I was looking for blood. It stuffed the alloy wheel, snapped off the wheel studs and damaged the disc rotor. I went in to the shop and spoke to the owner and told him that the service tech had forgotten to tighten up the wheel nuts. He was very apologetic and replaced all of the damaged parts including the alloy wheel ($800) with all brand new, I approached him gently and with respect, and he was great to deal with. The outcome may have been different if I went in with all guns blazing. If that approach doesn't work you can always try consumer affairs?
