Hello! I bought a ticket from Geneva to Grenoble on 6/07/2021. Order number is 1311288109.
The ticket was for 18.08.2021 at 14:59. Unfortunately, my plane to Geneva was postponed and now I can't be on such train. I've tried to return the ticket but it was impossible. So, I have 2 questions: 1) Why it is possible to make a return of money? 2) If the return is still not possible, can I change the ticket for a later time?
