This was the most frustrating part of my entire Phuket trip. The default collision insurance from the platform had a 10,000 baht deductible, and I didn't read the details carefully. Later, when using the car, there was a minor collision and I reported it to the insurance. The Vios we rented had a scratch on the left front fender and a small scratch on the left front light. They charged us 6,000 baht when returning the car. When I contacted the rental company’s customer service, they said I bought the basic insurance which meant the rental company could deduct up to 10,000 baht as they pleased, without following any specific repair cost - they only needed a receipt. When I noticed there was no receipt for the charge, I went back to the counter, and they were reluctant to give me one, saying I didn't buy the extra insurance. It made no sense - I paid the money and couldn't even get a receipt? After insisting for a long time, they unwillingly gave me one. When I asked why the charge was so high, they said it was because we didn't buy extra insurance, and they proudly mentioned that someone just paid over 8,000 baht for a damaged tire. For a beat-up Vios, it felt like we were renting a BMW. I bet they make a lot just from these charges. I complained to the platform's customer service, and they said they had reminded us but we didn't notice a small text note. I suspect many people have suffered as we did. If they truly cared for their customers, why not make the warning more prominent?
