Hello. I am new here, sorry if such question have been posed before, I looked but didn't find.
I traveled for a first time with the train and bought a ticket from a vending machine. I inserted a bancnote of 50 CHF, my ticket costed 30CHF, and the machine did not give back refund. I have pictures of the machine and the ticket. Is there someone I can contact about this?
Thanks in advance and kind regards
Milena
