I extended my rental for one day at the Melbourne store, and they agreed on 160 AUD initially. However, I was later charged 296 AUD and 396 AUD — two inexplicable expenses!

AVIS is really terrible!! We booked a car, but it wasn't available, so they just gave us another one saying it's the same class, even though they had already pre-authorized my credit card. We had no choice! No one checked the car with us. When we said the vehicle showed oil was low, the mechanic pushed it off to the office saying they hadn't reset it, and the office just pushed it back. It was an endless back-and-forth. And the rental platform just acts as a broker and didn't confirm whether the specific car was actually available. When we returned the car, they didn't check it either and just directly charged the pre-authorized amount from my credit card. I found out they overcharged by a few thousand dollars, claiming we exceeded the mileage limit. Thankfully, I had taken a photo of the odometer when we picked up the car. It was 35,000 km but their bill stated 34,000, an extra 1,000 km. They didn't inform us or verify and directly charged us. I complained two days ago, but no response yet. Luckily, I'm still in the country and planning to go directly to the store to discuss this.

The company is great, and the service attitude is good.

We were given a vehicle that had low pressure and a warning sign and then downgraded two levels with no refund to a Kia sedan that was quite unclean

There were a queue hence we had to wait for at least 30 mins to pick up the car. But service is good, location of car rental is just right next to the arrival hall. Easy to locate, car is clean and what I needed. Drop off is easy too.
