If FlixBus charged you twice for the same booking, it’s often a temporary payment error that can resolve itself within about 24 hours, so check your bank statement first.
If the duplicate charge still shows after that, go to the FlixBus Help Center’s “Problems with Payments / Double charge” section and use the contact form or live chat to report the issue with your booking reference, payment date, and screenshots of both charges — support will investigate and fix it.
If the issue persists, share your experience and consider filing a complaint on Xolvie to seek a resolution.
