Please use our help & contact area for all questions regarding your ticket bookings and for refunds.
The SBB Community is a public forum (customers help customers); please don’t post any personal data (names, addresses, e-mail, credit card numbers, ticket order no. etc.).
I advise you to buy a second ticket with the reduction half-fare card. With the both tickets, you will have the right price.
You can also contact my colleagues from the Ticketshop Support by e-mail: ticketshop@sbb.ch or by phone: 0848 030 030 (from 9:00-18:00) for a reimbursement.
