Hello Voitteephait81
Did you create an account to buy these tickets? It is recommended, you can see the successful orders in a list.
Did you check your spam folder?
After a technical problem, amounts are automatically refunded after a few days or the temporary reservations disappear, be patient.
If you cannot wait or the refund is never made, you can call the SBB Contact Center with this number:
+41 51 225 78 56 (24/7, waiting times may occur).
Kind regards
Danhiel
