Short-changed With a Smaller Car

The vehicle I selected in the booking process was a Toyota Corolla or equivalent. But I was given a Hyundai Accent, which is 1 class below than the Corolla (thus the low rating for size). I only came to realize on the 4th day as I picked up the car late at night and drove the the hotel where it was parked at the basement for 3 nights. The vehicle's front bumper and fenders was badly repaired. Front right fender was not flushed with the door and the front bumper was not properly secured. While I did not hit anything, the strong air speeds meeting the car due to driving caused left of the bumper to come slightly loose, and I was questioned for that when I return the car.
