I recently decided to move from London to Leeds and thus decided to travel by LNER. I intended to travel on the 27th of June but accidentally booked my ticket for the 25th of July. It was an online ticket and I didn't notice my mistake. At the entrance, I tried scanning my ticket but the system didn't let me through. So, I spoke to a guardsman who let me through. The ticket conductor also checked my tickets and give me the green light so I assumed everything was fine. It was only at Leeds Station where a guardsman noticed the incorrect date and asked me to give my personal details to the ticketmaster. I did as I was instructed and later received a mail in the post instructing me to provide a detailed account of the matter. I co operated and received a mail today instructing me to pay 226 pounds [a 90 pound fixed penalty and 136 pounds for a ticket]. I could accept paying the penalty but why am I being made to pay for another ticket when the ticket I used is set in the future? I would appreciate any help and advice.
