When I picked up my car, they gave me a BMW 320 station wagon, which is smaller than the Passat wagon I originally booked. The trunk couldn't fit three pieces of luggage as advertised for the Passat, which forced me to upgrade the vehicle. During the upgrade, the staff told me it would only cost an additional 20 CHF per day with the insurance fee unchanged. However, the actual charge was 25 CHF per day plus nearly 100 CHF in taxes (which the staff never mentioned). After emailing them, they blamed me and claimed they had informed me of everything. But when I returned the car and confronted the staff with the order, they lied again, saying it was 20 CHF per day plus 25 CHF in taxes, even though the order clearly stated 25 CHF per day and nearly 100 CHF in taxes. Simply outrageous!
