The reserved Galaxy model was not available, and the offered Smax didn't have enough space for six people. We had to consider upgrading to a Ford Tourneo by paying an extra fee. Initially, we were told verbally that it would cost about 13 euros per day extra. After agreeing to the upgrade, I had to go see the actual car myself, which was a hassle since the Tourneo isn't available in our country, so I didn't know what to expect. After agreeing to the upgrade, the paperwork showed an additional 16 euros per day, plus a 23.5% service fee and a 19% tax, which amounted to almost 25 euros per day extra. I felt somewhat cheated but had to accept due to time constraints. Additionally, regarding the toll fees for Austria and Switzerland, I was charged 25 euros. Upon reaching the border, I cautiously asked the gas station staff, and they didn't recognize the bill I had. I ended up having to buy toll fees separately for over 40 euros. Upon returning the car at the end of our trip, I asked the Hertz counter and was told that the CROSS BORDER FEE was for taking the car across borders, and toll fees still needed to be paid separately by me. Due to time constraints, I couldn't argue further. This wasn't just a money issue; if I hadn't been cautious and asked at the border, I might have faced fines or legal issues for not having the required toll stickers on the car windshield.
