Munich - Neuschwanstein Castle - Salzburg - Milan - Thun Lake - Zurich

The car pickup was relatively smooth, but I was inexplicably charged 140.59 euros after returning the car. After multiple communications with customer service, they admitted the rental company made a mistake by charging for late return and vehicle upgrade. As of writing this review, it has been over forty days, and the platform only refunded about 40 euros of the mistakenly charged late return fee a week ago, with the remaining 100 euros still unresolved. Multiple phone calls to customer service have been met with excuses that the responsible after-sales person is in a meeting or has left for the day, and requests to speak with a customer supervisor have been denied. As a consumer, the experience has been extremely poor.

Convenient

The service reservation phone number was unreachable; I don't understand why there was an error in the contract that restricted our self-drive to Germany only; Zuzuche should clearly state the precautions (e.g., payment methods and actual procedures are different, return signs...).

Reward

We picked up the car at Munich Airport. We arrived at 6:30 AM, and they only start working at 7:00 AM. They helped us with the car rental at 6:50 AM, which was quite convenient, although it seems there was some extra charge for early service. The car was in good condition. Returning the car at Frankfurt Airport was easy to find. Overall, we are quite satisfied.
