The staff at the Fox rental location in Los Angeles were extremely rude. First, they tried to sell us insurance, but we said we had already bought it on Zuzuche and didn't need it. They claimed that insurance bought on Zuzuche is invalid and not applicable in the U.S. When we insisted on not buying it, they got very unhappy and said that the Jeep SUV we rented was too poor in performance to drive to Salt Lake City, and pressured us to pay extra to upgrade to a Lincoln SUV. We insisted on keeping the Jeep we had originally booked. Then, they told us the Jeep we reserved was not available and offered us a Hyundai or Mazda of the same class. Due to time constraints, we had no choice but to accept. However, when I went to pick up the car, I found there were Jeeps available. It was clear they didn't give us the reserved Jeep because we didn't buy their insurance or pay extra to upgrade. Upon returning to Beijing, I discovered they had not only charged the $150 deposit directly as an expense along with the rental fee without pre-authorization, but they also overcharged by $10. When I contacted Zuzuche, they kept saying they would inquire with the car rental company and asked me to be patient. It's been 10 days with no progress. Again, I contacted Zuzuche customer service, and they told me to wait 4-8 weeks, and refused to say anything more! This whole car rental process, including the after-sales service from Zuzuche after returning to Beijing, has left me extremely disappointed. I promise I will never choose you again, and I will also tell everyone I know who needs to rent a car to never choose Zuzuche!
