Bothasig mall renovations damage my car.

the bothasig mall obviously have no care for OHSA. ive visited the mall to buy some stuff and fragments of rocks and cement landed on my vehicle. I noted a crack in my car windshield now on my way to work. I would like to know who will be responsible for the replacement of my windshield as i have to claim from my insurance. Management of bothasig mall this is not the first time your construction workers dont follow HSE protocal this time they damaged my car and i have photos
