A few years ago when I was on rotation in the U.S., I often used your booking website. The experience was great, the prices were fair, and the interface was in Chinese, which reduced the chance of misunderstanding. However, this time's experience has made me reconsider whether to directly book with a larger brand like Avis for my next U.S. car rental... This rental company insisted on not providing the originally reserved car. Initially, they claimed it was because we were going to Yosemite, even after explaining to the staff that we were not going there and evaluating the price difference, they still insisted that the originally reserved car was unavailable regardless of how long we waited and required us to pay an additional $20 per day. Ironically, we later saw the same car model in Yosemite... Additionally, we were also half-forced to add insurance and the option to return the car with an empty tank, which cost us over $100 more. They claimed it was more cost-effective, but after leaving, we realized that even if we used the more expensive gas, it would have cost only about $70 to fill up from nearly empty... In the end, besides the amount paid on your website, I had to pay an additional $500... Honestly, after a long flight to the U.S., I was already very tired, and I just wanted to pay to avoid delaying the rest of my trip. Renting the car became the only unpleasant part of the entire trip. For travelers who do not frequently visit the U.S. and are unfamiliar with the local rules, Dollar is really an unfriendly car rental company.
