They replaced my car with an SUV without informing me. Even after visiting the store three times, I couldn't get it changed. There was no one present when I returned the car.

Unclear charges for insurance - Environmental protection fee?

There were two staff members at the store, one German who was on the phone and an Asian standing by. When I spoke in Chinese to my companion to ask the Asian for help, he immediately replied in English to wait a moment and then pretended to check some documents. If he wasn't Chinese, how did he understand my Chinese and respond in English? It seemed like he didn't want to serve Chinese customers, very disappointing. The German staff member explained the contract very quickly. When I said I didn't understand and needed a translator, he got impatient when the translator device couldn't connect online, saying, 'Aren't you supposed to know English?' After explaining once more, he told me to sign with a clear expression of not wanting to repeat himself.

They gave me a much smaller car.

Downgraded the car
