When I clearly stated that I did not need additional insurance, the staff at Frankfurt Airport exploited the language barrier and only provided a German version of the contract, secretly adding the company's full insurance. Including various taxes and fees, I was charged over 800 euros.

Logged into the 'Zuzuche' website in China to pre-book a Mercedes-Benz C-Class four-door five-seat car and already paid (rental prices vary by car). On July 18, 2018, when picking up the car at the car rental counter in Frankfurt Airport, the German staff told us that no Mercedes-Benz was available and offered a BMW 3 Series four-door five-seat as an alternative, showing it on a computer screen. After confirming multiple times, we agreed to accept the alternative. Additionally, the staff tried to upsell a Volvo SUV, which we declined. When we went to the parking lot in Frankfurt Airport (about a ten-minute walk) to pick up the car self-service, we found it was actually a Skoda four-door five-seat. We returned to the counter to inquire, and the staff again said no Mercedes-Benz was available and only the Skoda was offered. We sternly pointed out, 'We rented a Mercedes-Benz as shown available on the website and paid for it. Therefore, the company should provide a Mercedes-Benz or give a reasonable explanation for why not, obtain our consent to provide an equivalent or higher-class car, and assume corresponding breach responsibilities. Additionally, claiming falsely that a BMW 3 Series would be provided is an attempt to deceive us. We demand a reasonable explanation and solution.' The staff then took out a key to a Mercedes-Benz from a drawer within two minutes without explanation. We successfully retrieved the car ourselves (a 2017 Mercedes-Benz C-Class 180 four-door five-seat car). Upon inspection, this was the only Mercedes-Benz in the dedicated parking area for the rental company at Frankfurt Airport, and it was a new 2017 model.

Avis at Frankfurt Airport is too bad! They really disappointed me. They destroyed my trust by charging me double insurance without any consultation, didn't explain anything, and didn't show me the contract. They just asked for my credit card and charged me 1500 Euros. Afterwards, despite many calls, they refused to correct it. Even Avis Landau called and emailed them, but Avis at the airport was still unwilling to correct their mistakes and didn't return the extra money to me. I had to drive 200 km to the airport Avis to cancel the old order, but even then, their bad service was evident again. They asked me to wait and didn't return the extra money, which really disappointed me. AVIS was very disappointing. They damaged the trust customers had in them. I had already informed them that I had bought full insurance in China through QEEQ, but they still charged me for another full insurance and refused to refund. They charged my credit card 1500 Euros. Resolving this issue took me several days and a lot of energy. Over the phone, they were indifferent and unwilling to solve the problem. In the end, I had to drive to the site to resolve it, which severely affected my overall good mood throughout the trip!

There were no obvious signs for the parking lot location, which was the only downside. The car's performance was good, and the service was also satisfactory.
