Thrifty car rental company secretly upgrades your vehicle without informing you, resulting in hidden charges. It's a rip-off!

The car's front bumper got a little scratched when moving over a curb. We reported it to the rental company, but the African-American lady at return said she didn't see any damage. After returning the car, we caught a shuttle to the airport. Shortly after leaving, the driver got a call asking if anyone had left keys behind, and we realized our son forgot to take our house keys off the car keys. We went back to retrieve them, and we were very grateful for their help.

No need to queue, but where is the promised Chinese service?

I read the rental policy several times. They require us to return the car with a full tank to avoid extra charges. However, the rental company imposed a prepayment for fuel when they authorized the card. No matter if you return the car with a full tank, they still charge this prepayment. Now, I'm trying to get this money back from the rental company, but it's been a month with no progress. Can’t the rental platform refund me first? Both the rental company and the rental platform refuse to reimburse me?

Like: pick up/drop off instructions were easy to understand. Booking process was smooth and efficient. Excellent value for money.
Dislike: At the rental counter i felt like i was unnecessarily sold an unlimited toll fee package which i didn't really need. And also looking back at receipt i seem to have been charged for a concession fee recovery which i thought fro my booking was included in the price.
