We notified the car rental company in advance about picking up the car late, but were told that there were no cars available unless we paid £15 per day for an upgrade. Even though we had already purchased full insurance through the platform, the rental company still forced us to buy additional insurance for £39 per day. Additionally, although we booked a vehicle with a full tank policy, a £95 fuel deposit was still taken. Without purchasing the additional insurance, our Visa card was not accepted; after paying £195 for the insurance, we didn't need to upgrade the car, place a deposit, and our Visa card worked fine. After using the car for 2 days, we refueled according to the rental agreement but ended up putting in the wrong type of fuel. On February 26th, with the help of passersby, we contacted the rental company. A rescue team arrived in the afternoon but couldn't fix the car and transported us to Bath, promising to pick us up the next morning to exchange the car at a nearby airport. The next day, we waited on the streets of Bath in below-freezing temperatures until 5 PM when the rescue team finally arrived. At this point, it was too late; we had to drive to our next destination, Windsor, for 3 hours in the night, which was too much for me as a 62-year-old. We canceled the rest of our trip and, with the help of passersby and the rescue team, took a bus back to London. We request the rental company to: 1) Apologize and compensate us for the suffering; 2) Cover the following economic losses: 1. Refund the Windsor accommodation fee of ¥627.98 for the 28th; 2. Refund the £26 transportation fee (since we had already purchased return tickets for March 1st, the £26 incurred on the 28th should be covered by the rental company); 3. Refund 2/5 of the rental fee; 4. Refund the so-called upgraded insurance fee of £195; 5. Refund the corresponding fuel deposit.
