Chaveirim Damaged the Car, Whats the Right thing to do?

My 17 year old son was in Monsey a week or so ago when he ran over a pothole and got a flat tire. He called Chaveirim. A very nice but clearly wildly inexperienced young man showed up. He was struggling to remove the tire off the wheel so he figured he’d kick the tire as hard as he can in the hopes it loosens up. As he did this a few times, he missed the tire and kicked the fender and put a nice sized dent into the car. I gave it some thought and figured to just leave it alone. My car is kind of old anyway. But what would be the erlich thing to do in that situation? Request compensation? Say something to Chaveirim? They are all volunteers after all but this was not ordinary negligence but rather supreme incompetence. If nothing else maybe they should have this fellow get a little training before he does something like that again. I am curious what the oilem thinks would be the appropriate thing to do.
