Luís Guia auto reboques

The owner who towed my car damaged my front bumper while towing it onto his reboque. And damaged it even further when dropping off my car at the garage. Owner said this is normal because of the steel cable. I asked the man if he had an insurance to cover for the damage done. Instead of admitting his wrong doing or cooperating he started threatening us and he made sure to leave the scene as soon as possible.Unprofessional, rude and doesn't care about damage done to someone else's vehicle.Police has been informed.
