I got them from the interpol website, yay!
The annoying part is not that the tickets sold out so quickly. Ok, demand is high. It's that the web thing was basically broken from the get-go. Unexpected behaviors with shows disappearing, tickets being reported as unavailable, yada yada. I mean, at the very least I'd expect you'd check out that your own presale link that you emailed to thousands of people was correct. Here's hoping they can improve their technology next time.
