Interesting the credit card company didn't help.
I would have thought that this would be a pretty easy "goods/services not delivered" situation.
Assuming, of course, that we are being told the whole story, and indeed there was no ticket emailed to him. "You charged me for a ticket you didn't deliver to me, for a service you didn't provide to me."
But heck, I know especially in Canada the cc companies try to wiggle out of this stuff.
