How can I return tickets?

By | November 28, 2019 | in

Dear Sirs, 
By mistake I've bought 4 extra tickets (return ones)from/to Paris-versailles (RER). 
My friend bought it for us but I just got to know when I had it already.
There's any chance I can return those 4(return tickets. All bought  last weekend.
Merci/ Thank you,
Patricia Silva
