car boot failed so I had to call out AA and waste a few hours while they were unable to fix it

Waited in line for 40 minutes, very slow. The most bizarre thing is, it was my first time in the UK, and they claimed I was on their blacklist and refused to rent me a car. I ended up using my friend's name to rent instead. When returning the car, they pointed out a very small dent and demanded £200. Such minor damages are easy to miss during pickup. After a lengthy argument, they finally dropped the charge. I bet the next person will get scammed too.

Never be late for pick-up. I thought since I paid the deposit, it wouldn't be a problem. But when I arrived, the order was canceled, the BMW X1 was not available, and the price had changed. I had to switch to another car at the last minute, which was extremely expensive. Don't even know if the deposit will be refunded. It's really frustrating to communicate with them. Also, the waiting time in line was extremely long...

1. If you don't buy insurance from them, you'll need to pay a deposit (around 20,000 RMB). 2. Be sure to inspect the car; any pre-existing minor scratches will be counted as your responsibility otherwise. 3. There's a daily limit of 95 miles; unlimited mileage costs around 8-10 pounds per day. 4. When calculating the cost, they overcharged us by 50 pounds, and reclaiming it requires contacting their company. We haven't received it back yet. 5. The final amount you pay will definitely not be what you initially saw on the rental site.

The longest wait and an error on my part cost me 4 times the original quote but there was no compromise on their part.

The ACE is not the real agency, but Green Motion, this resulted in an internal problem that made me wait more than 3 hours to get the car. I would never again choose this agency because of this, which should even be said before booking.
