I haven't thrown a hissy fit - I've changed my mind. In other circumstances I can get a full refund for goods I return.
Why should it be different for an event like this? The event has not happened and I have not even received the ticket.
I paid in good faith believing that the selection process would be fair and unbiased. It wasn't fair and was biased. Because of that I changed my mind.
I went back and checked your original post, and it stemmed from a basic misreading of the situation. You were getting your knickers in a twist about something that wasn't even real. And it was incredibly silly to have bought a ticket in advance of the result in that case too. That's not THEIR fault, though. That's YOUR fault.
Good luck with trying to get a refund then, because I would lay very high odds that you won't be successful. Your best bet is as advised above, ie to try to get as much of your money back as you can by selling it on Ebay. But if it is a specific seat, and only a single, then it's even more likely to go cheaper. So since the chances are that you are going to lose money anyway, you might as well just grit your teeth and make the best of it and go anyway. You never know, you might actually enjoy it. But at the very worst it will still be an interesting experience.
