Car damaged in car park

I stayed at the Garden Court in East London on the night of 21/12/2017. An altercation occurred in the car park during the night between some people during which my right fender and door was kicked in and side mirror pushed in. I noticed this the next morning and security said they didn't see anything. The Duty Manager Sylvia also mentioned that she couldn't see anything from the CCTV footage, which did cover the area of damage. This brings the integrity of hotel management into question, because they are quite clearly hiding something, as well as the efficiency and competence of the car park security, because an altercation of such a kind should have been seen and reported.
