Upgraded from EQA to EQS for only 15 euros a day, but an additional service fee was charged without prior notice.

The service was good, no need to queue, but they try to upsell you to upgrade the car, which is a bit annoying.

I confirmed the order with the car rental customer service before picking up the car, and received an email from the rental company saying the reserved car was ready. However, the counter told me the car I reserved wasn't available and recommended another model, claiming the diesel car was very cheap. The cost turned out to be more than twice the original order. My colleague signed the contract without looking carefully, thinking the doubled amount was a pre-authorization charge. What’s annoying is that the counter didn’t mention anything about upgrading the car. For such upgrades, informing the customer is the least they should do.

When picking up the car at Düsseldorf Airport, the staff kept saying that the insurance I bought wasn't zero-deductible and strongly recommended I add coverage (costing over 300 euros). Although QEEQ had already advised against believing the rental company's upselling, I ended up buying it again (previously got tricked in Spain). This time there was indeed significant scratching. When returning the car in Switzerland, I was met by an intern who didn't know much and kept saying I rented the car in Germany and he didn't understand German. I asked him to check the system to see if my insurance would cover it, and he kept saying he didn't know. The other staff also didn't help explain it to me. In the end, I still don't know if my credit card will be charged, making me feel very uncertain even after buying expensive insurance.
