Flixbus Driver Overcharged Me On Amsterdam-Hamburg Trip

On the night of April 19th, shortly before the shift to April 20th, the bus from Amsterdam to Hamburg, planned at 02:00, arrived about 03:30. The driver, a Frenchman with long black hair and glasses, didn't speak English. Despite arranging the first two rows weeks in advance, the driver refused to take our seats, claiming they were his. He refused to wait for us to contact customer support, insisting that if we wanted to board, we had to sit at the rear and pay an extra €70 per person. When we complained about the hefty charge, he gave us a "discount," claiming we could travel for €50 apiece. He refused to give us a receipt, insisting on paying cash, and physically pocketed the money. When we arrived in Hamburg, we went directly to the Flixbus center and explained the issue. While they recognized our complaints, none of this changes the nightmare we endured. Even if the initial ticket price is restored, the additional cost we paid and the possibility of being left there at that hour is something I never want to go through again. Even after we had boarded, the bus door would not close correctly, leaving us to wait for the driver to manually close it. I can confidently state that I will never utilize Kamil Koç for domestic, let alone foreign travel, again.
