Trentialia or possibly Unicredito as its bankers, seem to have a weird policy about repeat bookings on foreign credit cards. Recently booked Verona-Milan online using credit card. No problem. 24 hours later tried to book return. Three different credit cards (Amex, MasterCard, Maestro) refused, in each case requiring me to enter all details of the journey etc. before returning the same message that the card was not accepted. Fortunately was staying in a very helpful hotel (Spadari al Duomo, Milan) which booked the same journey using the hotel's card. They were obviously familiar with the problem. I seem to remember a similar problem two years ago. Have other forum members had similar problems? If so could someone persuade Trenitalia/Unicredito to accept that people booking several train journeys are not ipso facto undesirable illegal immigrants with stolen cards?
