The service is okay, but there's no Chinese service. Fortunately, I understand some English; otherwise, it would have been impossible to manage. The main issue is the rental policy, which feels like a bully contract. Initially, I booked to pick up the car in Chiang Mai and drop it off in Bangkok, so there was an extra fee for returning the car to a different location. Due to a change in plans, I switched to picking up and dropping off at the same location in Chiang Mai, but despite multiple attempts, the extra fee wasn't refunded. I find this unreasonable!
