The customer service actively recommended insurance and GPS upgrade, but later calls couldn't get through.

Quite convenient!

I booked a Peugeot 3008, but HERTZ gave me a Volkswagen. There was no space for my luggage, so I had to upgrade to a Volvo S60. Since I didn't communicate with the rental company in time, I ended up paying an extra insurance fee, which was quite a loss.

The return signage at the airport is not clear, and the return address does not specify which parking lot. Missed my flight because I couldn't find the return point.

Both pickup and return went smoothly, but two weeks after returning the car, I noticed an inexplicable charge of 60 euros for fuel and service fees. I immediately sent the return report and fuel receipt to the rental company, but it's been over ten days and still no resolution. Not sure if this is personal deceit by the staff or an intentional act by the rental company.
