Quoted from Tucks:

Did you buy on a credit card? In the UK, if you purchased on a credit card you'd get a full refund from the credit card company.
Why would anyone pre-order a game (or anything else for that matter) with no payment security?? If people stopped pre-ordering machines that didn't exist this problem wouldn't happen. If everyone waited until the company had a product to sell it would stop this all happening in the first place. Madness!
