Amsterdam-Cologne-Bonn

The rental company made me purchase another insurance without my permission, as the contract was in Dutch, and I initially thought it was a deposit. 200 euros feels like a rip-off. Contacted the rental service but they said since the contract was already signed, there was no way to get a refund. A reminder to other car renters: if you need full insurance for the car, it's best not to buy it from the rental app but directly from the rental counter. Otherwise, you might end up with two insurances. I've rented cars through the service 9 times, and 3-4 times I ended up with double insurance. The rental service should take some responsibility for this.

Almost no queue, simple procedures

If the customer forgets the credit card with their name, at least allow them to use a debit card with their name or the credit card of a companion in the same car. Due to this reason, I paid nearly 1000 yuan and couldn't use the car. If the car cannot be used, even if a full refund is not possible, at least a partial refund should be provided! Just like buying goods, when money is paid, service should be provided. If the service is not received, shouldn't the money be returned to the customer?

This was my first time renting a car abroad. The rental office at the airport had separate entrances and exits, which made returning the car a bit confusing. I hope they can provide clearer diagrams.

When I returned the car, I was asked where the back tray is, and telling me I will have to pay a fine, since it was missing. I answered it wasn't there when I picked the car and the guy said I should have mentioned it when they gave me the car. A part which you cannot see is missing. eventually they "let us go"...
