The pickup and driving experience were generally normal, but there were many unpleasant issues during the return. I wanted a refund for the unused days as I returned the car two days early. From another perspective, since it was a prepaid booking (which I found out through communication with the platform customer service), there was no clear refund policy. What truly frustrated me was the car rental company's uncooperative attitude. When communicating with the rental platform's customer service, they promised to provide a proof document but did not follow through. The invoice that was supposed to be emailed within three days also didn't arrive, and the attitude during the discussions was not good. Communication points never aligned, and they kept emphasizing their position as a sub-agent of SurPrice, stating that refunds require multiple levels of agent communication. While I understand the need for communication, SurPrice did not assist within its capacity. One of the responsible persons I was communicating with eventually disappeared, which was very unpleasant! This reflects the issue of too many agency levels between the platform and the final rental company. Supervision is necessary!
