I have rented cars from this company through your website twice before and had good experiences. However, this time the service was very poor. On August 10th, I was notified at San Francisco Airport that my reservation had been canceled. Since my English isn't good, I insisted on them checking again, and they found it was not canceled. On August 24th, when picking up the car at New York JFK Airport, I was asked for my international driver's license along with my Chinese driver's license, which they had never asked for before, so I didn't have it with me. Their attitude was very unfriendly. Fortunately, my wife had hers with her, so we were able to get the car.
