Avoid! Avoid! I advise everyone not to choose GREEN MOTION just to save a little money. They doubted my credit card and refused to give me a car without any explanation, even though my money was deducted. (Another couple also faced a similar situation due to credit card issues and had a big argument there.) We don't know if they want a specific type of credit card or if they're just trying to keep your prepayment. The app's customer service tried to help appeal but failed. Once the money is with them, you won't get it back—they will always have excuses. Extremely irresponsible! I learned a lesson for 2000 RMB. Renting offline later was more convenient and faster, with much better service. In short, be cautious unless you are absolutely sure your credit card is flawless. Even when I assured them my card worked fine in Istanbul, they still refused to try. So, sometimes it’s not the card but their perception of it. Ended up spending more money and time renting offline. Rent-a-car customer service was good and helped with offline rentals, and the app is fine. You can pick other companies, just avoid GREEN MOTION!
