The problem i think was a train from rome to florence so they changed it for another one and in a different date, i travel the 24 september and in my itinerary it says 22 sept. also it says that my confirmation is in progress. i just want to change the date to the 24 again or cancel it if that one is not available. please i need an answer, because i don't know if it was charged from my credit card.
