They left my veichle unlocked and returned it broken into and destroyed.
Made a police report and the officer said it was obvious that the only damage was done inside caused by being left unlocked.
My middle console is broke and I had stuff spilt all over the place.
I called the company and unless you can prove there driver did anything you're on your own even tho the car was under there care
