Waited half an hour for the shuttle and then another 20 minutes to get to the car rental company. I presented all the required documents as per the platform's requirements and paid online in advance. Once there, I was told I couldn't pick up the car because I needed an international driving permit. I called customer service, and they said they would coordinate. An hour later, they called back and suggested I switch to another rental company like Enterprise. I had to take a shuttle back to the airport and then another to the new rental company. I arrived in London at 1:30 PM, and by the time I got back it was almost 4:00 PM. I had an appointment at 5:00 PM, so I had to cancel the rental. I called a taxi, which cost me 30 pounds to get back to the hotel. It's been over a week, and I still haven't received a refund. An 8+ rating is ridiculous; is this company using us as guinea pigs?
