OP - sorry to read this... the money is not big....just the principal. But I’m glad to see your having a positive attitude. Please disregard the Debbie Downers, it is obvious you are aware of the nature of your tickets being non-refundable- it is also justified to ask if anyone knew a proper, up front work around—- actually you just asked if anyone knew an enail address so you could just ask - you weren't demanding anything nor making excuses.
While i have not mis-bought train tickets i have mis-hit keys while internet shopping. I need to punch key x and what do i do, hit key y, like my mind and finger were not connected...oh well. Last year i booked a $400 hotel room for an event in Monterey 8 months in advance. I later decided not to attend the event as I returned from a 3 wk Paris visit only a few days before but I totally forgot about my prebooked room until the Visa bill arried..,I was on the verge of screaming on the phone with Visa when i recalled that i did have a guaranteed reservation for that hotel and it thus wasn't a false charge—-oh well, live and learn.
