Help - Bernina Express and Glacier Express refund

Dear mates :-)
I am from China. I booked these two expressed online tonight, and at that moment I did not know with Swiss Pass I can take those for free.
Is there anyone can help me to refund my tickets? Because I really do not want to waste such a big amount of money.
Thank you very much.

Hi wangli1026,

I don't know where you purchased those tickets, but you best contact them directly. Usually unused tickets can be refunded, or at least most of the paid amount can be refunded.

That's good to hear. Enjoy your stay!
