I got caught sometime in August and i regret my actions a lot, I used to do it for a couple months around 4 times a week with one way being as costly as 20 pounds. I got caught at Gatwick airport which is different to where o usually did it, but said I had a 16 year old rail card as I was using the 16-17 prices. But I didn’t have that. What should I do now, I was on holiday for a while and have missed the deadline as the letter was sent during my holiday
