Got an Isuzu MUX instead of Toyota Kluger, pickup counter hard to reach by phone

We were hoping to get a Toyota Kluger but got an Isuzu MUX instead which has less trunk space. The car was quite new with 5000 km mileage. The off airport pickup counter was a 5 minute drive with the shuttle bus. It took me a long time to reach the branch by phone when i wanted to ask for directions to the shuttle bus pickup point. It took us nearly an hour to get to the pickup counter and get our car. Returning the car in Sydney airport was super fast.

Everything went smoothly. Good deal on the rental, thanks!
