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.
