I booked my car on Zuzuche with a payment of 811 NOK at the store. With the current exchange rate of 1:0.68, my rental cost should be 552 RMB. I added an extra driver at 4 EUR per day, which at an exchange rate of 1:8 should add 32 RMB. My total rental cost should be 584 RMB. However, my credit card was charged 758.52 RMB! Where did the extra 174.52 RMB come from? Please have Zuzuche customer service intervene and ask Hertz to provide a detailed cost breakdown.
