Hello Thacoulo20
Through this platform, we are unable to help with any issues involving personal data.
Since we are a customer support forum run by volunteers, we do not have access to the ticketing system. It would also not be secure to treat these questions publicly.
Usually, ticket validities cannot be changed. You may check with SBB whether there was a technical glitch, though.
Please ring SBB for that: +41 51 225 78 56 (24/7, waiting time may occur). From the U.S.: 011 41 51 225 78 56.
Kind regards,
Roland
