Never again! I booked six tickets through them on the 04th September 2018, 3 outward to Bergen, 3 return from Oslo. I checked, double checked and then finally screenshot the final screen so that I had details of the flights. There is zero doubt about the dates. Tickets arrived by email very quickly but three of the tickets had the WRONG date on them. I double checked against the screenshot, they are definitely wrong. Tried to call them, on hold for ages. Emailed them and got a response saying they would contact me in 24 hours. 36 hours later I had to call and emai again. Finally got through, on hold for 15 minutes, told someone would contact me to rectify. Finally got an email a day later saying it was my fault and they wanted £105 per ticket to change them! I explained about the screenshot, that their delay meant I could not claim under the Voluntary Airline Passenger Service Commitment and that I could prove they were wrong. They are not interested, they just kept asking for more money. I now intend to take them through the the European Small Claims Procedure in the Netherlands for the entire cost of the three flights, plus my costs, plus the costs of me traveling to the Netherlands to produce the screenshot, the emails and my telephone logs. DO NOT TOUCH THEM. They have totally ruined our trip.
