Hello [unbekannt]
Your question is not related to the topic above as you simply forgot to change the validity date of your ticket.
It is not possible to refund a ticket valid for today. Regular tickets can only be refunded before the date of validity.
Another question: you seem to travel in November which is the worst month to travel to Switzerland. Before you purchase tickets, you should verify that tourist attractions, cable cars & mountain railways will be operating as most of them are out of operation in November.
Kind regards,
Roland
