They kept saying I didn't book for two days. I contacted customer service and even showed them the bilingual order, but it didn't help. It took a long time, and they made me pay extra first, promising a refund. After returning the car, the staff told me to contact the rental company for the refund. I was really frustrated. At that point, I couldn't reach customer service. After a lot of back and forth, the staff finally said they would process the refund. If your English is not good, be cautious.
