Kuala Lumpur Airport to Downtown

The car's fuel gauge showed nearly empty right after leaving the airport. Before returning the car, I contacted customer service for nearby gas stations due to difficulty finding one. They directed me to another customer service representative on WeChat, but the WeChat number was invalid. I informed them in advance that I might be late returning the car due to searching for a gas station and peak traffic congestion, but received no response. When I returned the car an hour late, I was charged an additional 20 MYR, despite not exceeding the 24-hour rental period. Bookings within 24 hours should have the same rate.
