Hello DHARMENDAR
Welcome to the SBB Community. In Switzerland, greeting before asking a question is considered courteous 🙂
→ You are not purchasing a Swiss Pass. You are purchasing a Swiss Travel Pass.
→ If the payment failed, the bank will send you the money back. The amount is simply reserved, you did not pay anything.
→ Make sure your credit card supports 3D secure ID otherwise the payment will fail again. Then, fill in all data using full capital letters before sending the order.
Kind regards,
Roland
