Hello daphne_h
In this case, the purchase failed. The mony has been reserved on your account and will again be released in case of a failed purchase. It may take a few hours, check your bank account again.
If you had troubles purchasing the pass from SBB, I suggest that you should purchase from STC, the Switzerland Travel Center, the travel agency owned by SBB:
https://switzerlandtravelcentre.com/en/che/ticket/swiss-travel-pass
Their webshop is less restrictive in what concerns the acceptance of credit cards. The SBB webshop requires credit cards with 3D secure activated, otherwise the payment fails.
Kind regards,
Roland
