Sorry, let me be more specific:
I click purchase -> (for the 185chf choice)
Then, on the tab
For whom would you like to purchase a travelcard?
I click my data, which include my name, my adress, my postal code, the city I live in.
Lastly, i click on I’m not a robot, and hit continue –>.
This is when I’m transfered into a banl page, and i cannot continue with the purchase.
