Terrible service. Even though I showed the staff my order indicating I had already purchased full insurance, they insisted on adding insurance to the contract. Later, the staff claimed the extra payment was for fuel, but it included insurance, making me pay extra for insurance. Very deceitful.

1. Low efficiency, the queue time was extremely long. It took me over an hour when there were only five or six customers ahead of me; 2. They added over 500 euros in extra charges to the contract without informing me when I picked up the car. Fortunately, I spotted it and refused to pay; 3. The pick-up point is a ten-minute walk from the counter. The car was not filled up with fuel. After a long flight and long queue, I was too exhausted to argue, so I just accepted it; 4. At drop-off, they tried to charge an extra 460 euros. They handed me a 4-inch screen device to sign. I spotted it again and refused; 5. Everything was fine when I returned the car, but they still tried to scam me into buying personal and car insurance. This is just ridiculous; 6. Finally, they directly charged an extra 460 euros from my credit card without any signature or authorization, despite my two refusals. This is outrageous! Currently disputing the charge with the rental company and card issuer. 7. In all my car rental experiences across North America, Latin America, Africa, Europe, and Southeast Asia, Budget at Frankfurt Airport is by far the worst!

When returning the car, there was no inspection. They just took the keys and told me I could leave. Afterwards, they kept charging my credit card without notification, twice in total, amounting to over 1500 euros. I didn't receive any email detailing the charges either. I had already paid over 12,000 RMB for the rental, which included insurance. I hope the relevant authorities investigate this promptly and refund the charges.

Average experience, nothing special to mention

The front desk staff's attitude was average. The reserved model, a Benz A class, was unavailable, so I had to switch to a similar Mazda 3 diesel model. However, the car was very new, and its performance was exceptional.
