We were forced to buy insurance. I told the AVIS staff in advance that we had already purchased insurance on ZuZuChe, but AVIS said we hadn't and wouldn't let us pick up the car without it. Reluctantly, we had to pay. For two cars, each was charged $101.90. When we returned the cars, we tried to explain to the company again, but they refused to refund us, saying we had already signed the contract. We are very dissatisfied!
