1. The actual cost was almost twice the amount shown on the app. 2. Although the app already included basic insurance, the staff insisted on purchasing full insurance, which resulted in double coverage. Even after returning the car, I still haven't seen the insurance policy. What happens if something goes wrong? All the risk is on the customer. 3. I never saw the official rental contract, only a vehicle inspection checklist. 4. The app included the option to return the car at a different location, but the store still charged extra fees. 5. No itemized receipt was provided.
