I rented two Mercedes E-Class cars, but was given an A-Class and a Hyundai hatchback instead, and they kept insisting they were the same category. Later they claimed as long as it's a Mercedes, it's fine. When we pointed out one was a Hyundai, they had no explanation. We ended up not picking up the car, had to call international customer service to switch companies, wasted three hours and almost an hour on international calls. Terrible service.
