My nearest station is unstaffed and has no ticket issuing facilities, so I have purchase my ticket from the guard on the train. How practically every time I buy a travelcard it refuses to operate any barrier. This is getting beyond a joke now, and tonight I had to quickly get through the barrier after someone else at Russell Square because there was no one to let me through. I've emailed SE about this and they just gave me a fob off reply. I'm tempted to refuse to buy a ticket from the guard and insist on buying it at Sittingbourne.
