So much hate.

Some time ago my "25% DB Card" ran out and was not active anymore, but the app did not display a warning. Even when buying a ticket from the app, it still had the "25% off" option activated by default.

Result: huge fine (something like 200 euros) on the train + I had to buy a completely new ticket (another 100+ euros) because the ticket I had bought ( which was 75% of original price) was considered completely invalid. I tried in all possible ways to get this fine reduced, as it was an honest mistake and arguably caused by their UX, but they did not budge.

I hate hate hate Deutsche Bahn with a passion, yet I still use it cause I'm an idiot who doesn't want to fly for short routes.
