hello everyone,

 

I won the interrail ticket via Discover EU and I began booking my trains. One journey goes from Paris to Valencia. Accidentally I booked the journey for the wrong date. I want to travel one day earlier. I also used two of my four credits to book the seat reservations. 
 

I’ve been researching on how to change the seat reservations but I couldn’t find any results so I wanted to ask wether someone knows how to change the date. 
 

thanks for your help!
