yeah this is exactly why they are call Stealerships. The car is under warranty, you want it in perfect running order before it leaves the lot. the fact they have the Audacity to even tell you to come pick up the car tells me they are a horrible service department. See if you can’t locate the E-mail or contact information for the owner of the stealership and notify him of the situation. I bet the issue is resolved with in a few hours. unless the owner is a complete asshat as well. but thats a future problem.

Start with some soap and steel wool. clean the surface as much as possible. this will let you know what the next stage should be. Rather it is a hard sand or just a re-chrome/Paint. It looks like there is a bit of pitting there so it is likely going to be a hard sand. after that I would have them re-chromed
