I rented a car from europcar perth. I lefted our Tomtom GPS navigator in the car by accident.After contacting europcar and explaining this ,they said they needed 7 working days to reply.I had to contact them in the finish to find they new nothing.Since I had locked the car and had returned the key to europcar staff,I can only think there staff have it.I will go back to the more trustworthy rental car companys in the future.
