Hello Muratcan
A refund of a Saver Day Pass is impossible.
Please check with the SBB Customer Service since you purchase a Saver Day Pass for the wrong customer group:
+41 51 225 78 56 (24/7, waiting times may be possible).
When you purchase regular point-to-point tickets, make sure you purchase those at full fare!
Btw, our local tender is the Swiss Franc, CHF.
Kind regards,
Roland
