Bad customer service
I was searching for an eco-friendly way to travel from Larvik to Uppsala. In Rail Ninja, it said I should book the first part of my train ride (Larvik to Oslo) separately, which I did. That first train was incredibly delayed. I tried to contact Rail Ninja to change the time of my ticket, which was not possible. I understand that bureaucratically they don't have to change the time of my ticket, but their own website said that I should book it separately. Good customer service would just help a customer in a situation like this, it is out of my control and now I'm stranded. The ticket was incredibly expensive for me...
