Drunks have scratched my car!!! What to do??

Hello together… So as in the title already written 2 drunks scratched my car. The whole thing happened this We. at a Geb. celebration. There two present had not loved each other so much and wanted to hit their heads outside between the cars. My girlfriend saw that the two of them thundered to my car. Now I have a scratch that attacked the paint. So not up to the metal but only in the paint. And a second thinner that goes up to the metal The next day I was with the police and they meant that I will not have a chance with an ad. Since they did not do this on purpose. So so on keys out and fast…. but just fell to the car… I bought the A6 only used about 2 months ago. I did have a partial cascade, but would have to pay 300€ self-retention za But I don’t see why I should pay for it, just because two are so stupid and with the cars… .. maybe someone already has experiences with similar situations? Should one give such a thing to the legal protection? The policeman meant I should make the ad on vandalism and bite in the sour apples. My insurance man told me, however, that I should report this and just the names of the two should stand inside. Then I would have to pay it myself. I hope you have a tip for me… Thank you very much for greeting PS.: I don’t know the two of them, so I can’t figure it out with them either. And one of them already has to pay 1000€ of them…
