Seat24 — Credit card charge
Seat24.de presents its booking system with a German website. Wenn booking a flight the come up with a huge creditcard fee of 9€ (in my case 5% of the booking Value!). But they also propose a possibility to avoid these charges when paying with American Express (AMEX). As you can see on the screenshot they propose the possibility but you can can chose it in the menu (see screenshot).
I complained about it in German and I received an answer back that they only speak english (not exeptable if you present your offer in German with an .de website) futhermore they refuse to reimbure my 9€ credit card fee.
I would say avoid this website, its a scam!
