Has anyone ever won anything off the Xbox Community Competition site before?

I've entered a few competitions on there in the past and, during a recent Google on myself, I got a hit off the Competitions Winners page. I duly checked and found I'd won a copy of Pro Evolution Soccer 2009 from the December competition.

The thing is... I haven't heard a thing from Microsoft/Xbox about this. I've even checked my old email addresses but there's nothing. Admittedly, I hadn't set up the full contact details part of my profile but, at the time, all that was required was the email address. Funnily, I found a forum thread on another site with people who haven't heard anything either.

I'm wondering if there's been some snafu at Microsoft/Xbox or something else.

[edit]I emailed the contact email address on the site a few weeks back but got no reply.
