The car condition was very poor, with the engine light turning on at one point during the trip. The rental company claimed to have WeChat, but in reality, they only had WhatsApp. Without WhatsApp, it was impossible to get in touch, and they kept shifting the blame. I did not receive any phone calls or emails regarding the confirmation of the return time. When I wanted to return the car early, the customer service directly said it was not allowed. I told them I wouldn't make my flight, and they responded with no solution and a very bad attitude. Additionally, due to high temperatures, the battery and engine warning lights kept flashing. When I called the rental company, they insisted I send them a video via WhatsApp for verification. So, does that mean without WhatsApp, there's no way to communicate with you?
