Went to a restaurant to celebrate my dads birthday with the rents, after the meal came back to find 2 little scratches on the drivers door below the door handle (like a little claw mark) each one about 5mm long... Someone blatantly hit their door into mine. im absolutely gutted.. the car is only about 3 weeks old.. whats the best thing to do? (appart from finding out who did it and cutting their balls off)
