Hello Deeshoixee88
We are a customer support page run by travel experts; we are not the SBB customer service officials.
Then, the payment was not successful so was the purchase; the amount will be back on your account within days.
Every successful purchase is confirmed by a payment confirmation e-mail.
Make sure it did not end up in the SPAM folder, and your credit card supports 3D secure ID authentication; furthermore, try entering all payment information in full capital letters.
Kind regards,
Roland
