Communication between Zuzuche and the overseas car rental company was completely unsuccessful. I completed the booking on the Zuzuche website and arrived at the Hertz car rental at Melbourne Airport on the morning of May 12. The car rental agency told me they had no information about my booking. I tried to contact Zuzuche for over an hour with no answer. I was stuck at the car rental office for more than two hours without a car, which disrupted my travel plans. I had to make a new booking directly with the car rental agency at a much higher cost than my Zuzuche booking.
