When returning the car, I had definitely refueled it completely, but I didn't keep the receipt. During the inspection, they insisted that the tank wasn't full. I explained multiple times, and they still said they would refuel it. If it was less than 5 liters, there would be no charge, otherwise they would charge me 29 dollars. Later, I found out they charged me 29 dollars. Also, renting a child safety seat for 3 days costs 80 dollars, which is too expensive. My friend also booked a car with me but forgot his credit card. The rental company refused to rent the car to him and wouldn't refund or cancel the reservation. We decided to rent a car on the spot, but the company quoted us 1000 AUD per day, which is ridiculously high.
