I have made a reservation for a sleeper train on the website “https://www.sbb.ch/,” but I am unable to find the reservation details. The payment for the reservation has been completed with the name “SSB CFF FFS Ticket Sho” appearing on my credit card statement, but SBB does not seem to have any record of it. I would like to either confirm the reservation or cancel it and make a new reservation, but I don’t have a reservation number, so I’m not sure what steps to take. If anyone knows how to help, please provide a response. Thank you.
