Hi I put a wrong departure date for a three day swiss pass and booked online through the official swiss SBB
So,I wanted to cancel the tickets.I have filled the online refund form and furnished all the identity proofs and tickets.As I have purchased the tickets on 30-June-2021 and departure is also same date.Is it possible for a refund.
I wanted to do another booking with correct date.Please help me in this case.
