I want to buy a Half Fare pass for my upcoming trip to Switzerland from the U.S. I created a login with SwissPass. It then asked me if I have a Customer Number, but I do not. It asked me to Register, and then asked me to do an Identity Check. Then it asked me to put in my mobile number for the Identity Check. When I did, it said that some problem had occurred and that I should try later. I looked on the website for the Chat function to get help, but the chat button was faded out (compared to the red buttons for other choices), and when I tried to click it nothing happens. So I am at a dead end. How can I get in touch with someone at SBB who can sell me the Half Fare Pass, and sell one to my wife as well?
