Hey OP sorry to break it to you but these wheels cannot be POLISHED or BUFFED out with those scratches. Just like NolteAudio said,these wheels are laser etched, not polished. That is what gives them the reflective gloss.
You need to demand more than just buffing them out as they are in the wrong here and screwed up more than just one wheel.
As BeatItHelmet said above, he is a service manager for a dealership, whether small or large, and even he would replace them.
I have a set of RS4 reps on my GTI and had them custom painted before I had the tires put on. I went to a reputable shop that I have gone to for many years and even they couldn't guarantee that the tire would not damage the paint/clear coat. But I went ahead and he did a fabulous job. Sorry to hear bout this. Shops like this need to pay for the damage so that they learn what NOT to do next time.
