I was trying to book a seat reservation throw the eurial app for the train from Paris to Amsterdam but I couldn't find any availability
then I went throw a website called b _ Europe and booked a seat reservation for a train belongs to thalys
And sadly I found our that I booked 15 May instead of 14 May
15 minutes latee When I tried to edit the date it will coaste 264$
And in the euro app I couldn't cancel the trip they said that means that I used 1 travel day
And I really don't know what to do
