Hi I have tickets to Milan that I need to cancel. The order number is TRE654606. I have a ticket for 10/16 at 22:50, train number is 1910, and one on 10/18 at 23:03, train number 1911. It says I should be able to get a refund if I cancel within 24 hrs. The other tickets I purchased I see are non-refundable and that is fine.
