Hello, I requested a refund for some train tickets that I could not use because the line was not operational. (Interrupted service Meiringen - Interlaken Ost Duration:13.08.2024 - 24.11.2024). I bought the alternative tickets with a stop in Meiringen + bus for the same day. Even so, they applied a 10 CHF fee on the refund. Can I claim these 10 CHF? Thanks
