Hello, I’m trying to buy the tickets I need for my family trip on September 23rd, but since Saturday, neither the app nor the website will allow me to complete the payment. I’d like to know why this is happening. On the Bernina Express website, I was able to purchase the required seats, but I haven’t been able to buy the ticket, which is sold by SBB. I’ve tried with a Visa card and also with another Mastercard, and the payment has been declined. Perhaps there are some countries with payment restrictions? I would appreciate any help you can provide so I can resolve this and complete the purchase. Thank you very much.
