1. Delayed car pickup with a bad attitude. 2. Numerous after-sales issues after returning the car, especially when booking through a third-party platform. They shirk responsibility and make unfounded charges, repeatedly charging misconduct service fees without any proof. 3. Many hidden issues: firstly, due to the domestic rental platform acting as a middleman, and secondly, neither the rental platform nor Avis could provide sufficient evidence for the so-called violations and violation management fees. Users are inexplicably charged on their credit cards! There is no way to complain or appeal!
