I commanded a ticket on April 9 2023 for 7 days within one Month starting 1st June2023
I used this ticket for 4 Trips between 1. and 9. June and arrived in Nantes La Baule France.
There I spent some days with a friend and I did not use my Smartphone because I had no possibilty to charge it and we had no Internet Connection. When I wanted to look at my ticket some days later, I read that it was expired. For continuing my trip to Bordeaux and for my trip back to munich I had to buy new tickets and I got big troubles in the train. I could only show my reservations to the controller but I had no valid ticket on my smartphone.
How can I get my money back?
