My daughter has been lucky enough to win a photography competition. We received our train tickets today for a trip to London to receive her prize. The company involved has sent 2 Adults and 1 Child ticket. I rang them to inform them that I'm a single parent and I wouldn't require the second adult ticket and did they want the ticket back tomorrow so they could claim a refund back. They said don't worry about it. Is there anything to stop me getting this refund myself or even just selling the ticket on at a reduced rate myself outside the station tomorrow?
