APS Damaged and soiled my vehicle

I arranged parking with APS from 7 to 9 February 2016. Upon receiving my Nissan Primastar minibus back there were fresh and deep scuff marks in the side panel's near the rear wheels on both sides. There was a list of numbers added up and tick marks in the middle of the drivers seat upholstery!! This was seemingly from carbonized paper placed in the seat, to use the seat squab as a backing. The rear parcel tray was lying in the luggage space at an angle. This happens only when hitting speed bumps at high speed! The left has rear seatbelt was dangling and the buckle was hitting the window while driving. On closer inspection I found that the tensioning device had been over extended, Why??. The carpet in the load are had black treat marks that weren't there before.
