The staff is extremely unprofessional, dishonest, and unethical. A car rental order with supplementary insurance paid in full 7 months ago was not fulfilled according to the terms specified in the order. Despite having over 200 days to freely change the order, vehicle model, and insurance types, they claimed 'will return to you'. Is it reasonable that the daily cost of an automatic compact car is higher than that of a BMW or Mercedes? The store charged additional fees that were more than double the already paid full cost, including supplementary insurance. Is this called professional?

Previous rental did not include insurance. The Avis staff added insurance without informing us. Be cautious of this pitfall when renting a car.

It was convenient to pick up the car following the signs at Frankfurt T1. I switched to a VW Golf DTI which was a bit more expensive but worth it. Drove up to 200 km/h, thrilling! Returning the car was a bit tricky with the GPS, easier to follow the airport signs, T1 arrival, then follow the car rental directions.

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!
