Flix Bus should be avoided for their complete lack of professionalism, customer care and failure to follow up on serious complaints. On attempting to board at Bratislava for Vienna, I was verbally abused by a driver for no apparent reason other than asking to confirm the bus's destination shortly before departure. Despite making it clear I did not understand Slovak, he continued to shout at me for a prolonged time. Later, as the queue started boarding, I was again shouted at after presenting my ticket. Again not understanding the issue - and having left plenty of time for the driver to scan the QR code - I attempted to board, whereupon I was grabbed and physically manhandled off the bus. At this point, several other passengers intervened with the driver on my behalf. I asked one who spoke Slovak what the issue was, and was told "the guy just hates his job and is having a bad day". When I complained to Flix Bus customer support I twice received a generic copy/paste reply with a mealy-mouthed apology for "inconvenience caused" and that "your experience did not match your expectations". Both failed to address my complaint or request for disciplinary action against the driver. After this absolutely pathetic response by Flix Bus, and on reading multiple similar complaints by other customers, I will be avoiding them from now on.
