Does anyone know how to contact Flixbus (Europe)? I can't see anything on their website except FAQs. Thank you!

If you go to the bottom of the home page and click on Customer Service Help it comes up with a whole range of categories you can choose, followed by FAQs on that category. At the end there is a contact button which produces a standard contact form. Try choosing the category closest to you need and pressing contact to fill in the form.

Good luck!

Thanks heaps, hetismij2! I've successfully sent off my query.
