Hello, I'm writing because I just bought a ticket from the SBB website, and after looking at the tickets, noticed that the birthdate for one of the birthdays was incorrect. I have tried to call all your phone numbers, but none of them work. I saw that I can refund the ticket through a form, but it will charge me an extra 10 dollars. I just want to change the birthdate, not be charged 10 dollars for an issue caused by the website dropdown menus. I also tried to refund the tickets immediately, but it didn't work. Is there someone I can email instead of call, as I cannot get in touch with any of the phone lines? Guidance would be greatly appreciated. I am in the US, if that helps. Thank you!
