Avoid RegioJet at all costs! If you value your time, money, or sanity, steer clear and opt for Czech Railways, Flixbus, or Leo Express instead. RegioJet's customer service is the absolute worst. They don’t honor their agreements, and their incompetence is beyond belief. My train was delayed over 8 hours due to floods, and to make things worse, they lied right to our faces! The stewards and the onboard announcement both confirmed there were technical issues in addition to the flood, and told us to go to any RegioJet cash desk for a full refund. I asked them multiple times, and they assured me it would be refunded in full. But when I finally got to their kiosk in Prague, they flat-out refused to refund my ticket! Suddenly, the delay was only because of the flood, and technical issues were no longer part of the story. I tried to explain what the staff on the train had said, but they were rude, dismissive, and had the audacity to laugh in my face! Completely unprofessional and outright disrespectful. They told me to leave and didn’t care one bit when I said I’d escalate it. Their so-called "customer support" later sent a generic apology, which made it crystal clear—they don’t give a damn about their passengers or taking responsibility for the mess they caused. To top it all off, Czech Railways handled the same issue like true professionals and compensated all of their passengers. RegioJet, on the other hand, couldn't care less and offered zero support or compensation. Absolutely disgraceful! If you want to avoid a nightmare, do yourself a favor and choose any other company. RegioJet is an absolute joke, and I will never, ever travel with them again.
