The second part of my journey is billed directly to my company each occurrence. I have setup the corporate payment details in the past (2 years ago, and checked they are still correct). Until last week it worked without issue and now I am receiving the error code TIF-3018 Payment method not found. However if I try to buy a ticket for a longer time in the future it seems to work fine. But buying a ticket just before I board the train (which is what I need) it fails and I have to change the payment to a personal credit card.
Thanks in advance for your help.
