They didn't mention any car damage when returning the car, but claimed there was damage the next day and charged me for it. Is this appropriate? Full of lies, do they think Chinese people won't bother with a few hundred bucks?

First, let's talk about the store. The Antalya Airport location seems to be merged with another company. It was hard to find, and we only stumbled upon it by accident while asking for directions. They promised someone would meet us at the exit, but no one was there. When picking up the car, the staff knew nothing, not even if the car had an HGS. They didn't speak English, making communication impossible. Eventually, another store's staff had to help us. This is a terrible rental company. Do not be swayed by reviews. Having just returned home, I can confirm they are very bad.

Average, neither pickup nor drop-off was very convenient.

Too few instructions, and you need to call ahead since there's no one at the airport to guide you. Not everyone has a local contact number, and how do you contact someone right after landing?

Nice clean car and friendly staff
