Hello BlancoHerrera
Did you create an account to buy these tickets? In this case you can check the order list. Another possibility is that the E-mail address was false. Did you also check your spam folder?
After a technical problem, amounts are automatically refunded after a few days or temporary reservations disappear, be patient.
If you cannot wait or you never get a refund, you can call the SBB Contact Center with this number:
+41 51 225 78 56 (24/7, waiting times may occur).
Kind regards
Danhiel
