It sounds like you’ve already lifted the payment limit on your phone, but you’re still unable to book high-speed train tickets online. This can be frustrating!
Can you tell me more about what’s happening? Did the website prompt any error messages or ask for additional confirmation when trying to purchase the ticket? Or is it simply not allowing you to proceed with the booking process?
Additionally, have you tried clearing your browser cache and cookies before attempting to book the ticket again? Sometimes, this can resolve issues like these.
Let’s try to troubleshoot together!
