Hello Astroneer90
Thank you for your message. It’s important that the name on the half fare pass matches the name on your sister’s identification documents. Using the wrong name could lead to complications while travelling.
In this case, it would be easiest if you make the refund yourself and then book again with the correct name. You can do this directly via our website. Click here to go to the refund form.
If you have any questions or need support, you can contact our customer service team at any time on 0848 44 66 88 (CHF 0.08/min.). They will be happy to help you.
I wish you a pleasant day.
Greetings
