The service at the car pick-up location was decent, and it took about 10 minutes for both picking up and dropping off the car. The problem handling was unsatisfactory. The car’s air conditioner broke on a hot day. We could not reach them by phone during business hours, and had to email for help. The email response asked us to call their office, which then redirected us to call the car repair service. The repair hotline couldn't see our caller ID and couldn't text us the repair address. When we asked for an email, it took forever, and when we called again, they suddenly could see our number and texted us the address. We had to visit the repair shop twice. The first visit they were too busy without an appointment, and the second visit after waiting for an hour, they told us they didn't have the necessary parts and advised us to endure until we returned the car. Later, the rental company called and offered us a discount but couldn’t specify how much. At the airport, they claimed they'd never heard of any discount, and we had to email for assistance again. After insisting, they found a note from a colleague and gave us a one-day rental discount. Considering we rented the car for 13 days and endured the heat, the 0.76-day discount as compensation felt ridiculous and frustrating.
