****** Property in my vehicle

I had sent my car to the carwash at Total Energies in East london. Since it was not my first time there I did not check my boot but it was only when I got home and checked my boot to find that two bags with all my clothes had been missing. I went over to the garage to ask and was shown cctv footage, however they did not show everything just the car at the drying bay. All my clothing is in those bags and I was told that there is nothing that can be done.
