I don't want to blame the staff at the Frankfurt Airport T1 counter, as I think he did the right job suggesting me a gasoline car instead of an EV (although I wonder the Mercedes was a reasonable option). With the change of car I was charged quite a bit at the counter additionally, but that is still understandable. What confuses me is the mysterious 30EUR additional charge on my credit card 1 month after rental, as well as the fact Eurpocar never replied to my request for sending me a full invoice via email. At the end, their website's contacting form doesn't allow me to send this claim due to some technical error on the website. I hope I'm the only one with this kind of experience.

I don't think QEEQ had any role to play in this confusion.

Quick service, short waiting times

Very satisfied, they answer all questions.

Good

We recorded a video during pickup showing an issue with the rim. When we returned the car, they claimed there was a problem with the same rim. We showed them the video, and they verbally acknowledged it and said it was noted and there would be no charge. However, four days later, we were still charged.
