The originally booked SUV was not available and was downgraded. When we got the keys and entered the car, the safety lock was broken, which was unsafe especially for children. We switched to a second car, only to find the air conditioning blew out hot air. After much hassle, we switched to a third downgraded car, wasting nearly 2 hours (from the original 1 PM to nearly 3 PM). In a hurry, we took the third downgraded car, but soon discovered it had no GPS and not even a USB port. During our 4-day Melbourne trip, we had to navigate with 3 phones taking turns. We couldn’t listen to music or take photos to save battery for navigation. Charging phones became our top priority every night at the hotel, or we couldn’t use the phones for navigation the next day. In desperation, we bought a car USB port, which didn’t work in the car but worked fine in a friend’s car, proving the car port was broken. Terrible service!!!
