The charged too much money from my card.

The last time I refueled, the nozzle shut off prematurely, so I thought the tank was full. It turned out to be about 10 AUD short. By the time we got to the airport it was already dark, and since we spent a long time looking for the drop-off point, we didn't dare to drive back out to fill up. As a result, we were charged 50 AUD. When picking up the car, the staff did not mention that the car had to be particularly clean. In New Zealand, we only did the necessary cleaning when returning the car and weren't charged for it, so we assumed Australia would be the same. As we didn't have vacuuming equipment, the kids ate snacks in the car and left crumbs behind, making it hard to clean thoroughly. Plus, we didn't see any car wash places along the way. Consequently, we were charged 90 AUD on our credit card. I'd like to remind fellow travelers of these two charges.

It's hard to describe my impression of the rental company. The Australian female employee at pick-up was quite clueless; I forgot her name. Later, a Chinese guy named Steven helped us a lot and was very reliable. I want to give Steven a 5-star rating, but the woman was really frustrating.

Cancelled last minute claiming no cars available.

Up until now, there's been no resolution to the issue. They previously said something about international customers and that a result would come out in 1-2 days, but it's been half a month with no result.

Overcharging. It was supposed to be around 800 RMB but increased to over 1800 RMB. The young driver insurance turned out to be the main reason for overcharging. Honestly, it shouldn't cost that much. They charged an additional 260 AUD on top of the 800 RMB. The car rental manual provided by Zuzuche offered no effective solutions for compensation or prevention of such issues. I wanted a Mitsubishi car due to budget constraints and not wanting to spend too much on the rental, but Thrifty changed it to a Qashqai without notifying me, even though the car I wanted was clearly available in their inventory.
