If only I had known this deal earlier! :-)
But you gotta hit that refresh button more i think. I got my ticket at 10:10 AM. am not lying. I think the website couldn't handle the load and let out only a few tickets at a time. And it was showing unavailable even when it wasn't sold out! Sometime around 9:45 I got hold to one but screwed it up for 'verified by visa' shit.
Anyway, I wish you luck for next time. Also, I can help if the booking's on a weekend. :-)
