To cut long story short... A week on sunday Sunday my dad and I are travelling on the Charity Railtour's tour from London to Crewe one way. We booked the tickets from Wycombe to Euston and Crewe to Wycombe from Train split. Today on my way home from school I went to collect the tickets and the machine printed 6 out of 8 tickets out. It completely missed out my advance single from crewe to wycombe plus reservation from crewe to London. I asked the ticket office guy to check the machine and he couldn't find it, nor could I. Any suggestions on what I should do?
