Hi Can anybody shed some light on how i could challenge this please? That is, if i can challenge it. My offspring used the train last month without tapping in & was stopped by an inspector i presume? (Sorry i haven't used a train in a long time & have never had a penalty notice so don't quite know how this works) Inspector took name and address (said correct address &door number was given) but the follow up letter and possibly the original PFN went to a neighbour's rather than ours so i was non the wiser until the neighbour posted this through the letterbox one afternoon. Apparently the inspector asked why offspring didn't have a ticket. Offspring who is 17 btw with ASD explains barriers were open, so walked through without tapping. Inspector explains that shouldn't have been done and proceeds to ask for oyster, took address & name and says it was fine to go afterwards, no mention of a penalty being issued or a fine. There was money on the 16+ oyster for the train journey. How do i approach the issue with wrong address. Oyster is registered to our correct address yet somehow it appears the PFN was addressed to an different door number.
