I had a terrible experience with this car rental. I'm still not sure if I got scammed because I'm naive or because this platform takes advantage of customers. I strongly advise against using this app for car rentals. I'll never use it again in my life! When I arrived in Paris, I saw a sign at the airport and approached it to find out that my reserved car was unavailable and I needed to switch. I was willing to change, but there were no cars in the same category, so I had to book a different one. After completing the new booking and paying, I asked the clerk what would happen to the money I paid on the platform. He said it would be released. I'm not well-versed, does 'release' mean the cancellation of the order on the platform? Then I was given a bill in French and asked to sign it. I don't understand French at all. After signing, I realized I had actually paid an upgrade fee. What was verbally communicated to me was different from the contract. They took advantage of my lack of understanding. When I got back, it felt like I paid twice for one rental. When I contacted the platform, they said I should have contacted them at the time, that I should have received a free upgrade, and gave me endless excuses. This dragged on for six months with no resolution. I accepted my bad luck, but I strongly warn everyone to never use this horrible platform. It brings nothing but endless trouble to customers! Absolutely terrible experience!
