Basically still satisfied, rented a new New Year car. It was only when I finally settled, I suddenly deducted $25, I was a little confused. I don't know if the other party told me that it was the credit card that I deducted it myself. Later, I asked the initiative, only to know that it was deducting my extra mileage fee. But I clearly said in the order that there is no limit to the mileage, and the result is discussed with them. There is no result and it is a bit complicated. I simply called Trip.com customer service and asked them to help me solve it. At present, although the payment has not been returned to the credit card, it has been communicated at least and refunded within a few days.
