We reserved a Via Verde transponder device in advance, but were told it was out of stock upon arrival. This made navigating the complex Portuguese highways very inconvenient and resulted in excess toll charges. The original car model we booked was unavailable, and the replacement car broke down. After the vehicle was towed, we were overcharged for fuel. We had to travel to the airport to get another car, incurring additional expenses. Although we initially booked the car for three days, we only used it for one and a half days. At the very least, we should have been refunded for one day's rental. They also charged us extra fees due to supposed changes in daily rates for early returns.
