NEWS: don't worry if you haven't received your ticket yet, I mailed the AXS customer service and this is what I got:
Thank you for contacting the O2 Customer Services / AXS Support UK. We would like to apologise for any confusion as well as the delay of your e-ticket delivery. e-tickets for the NBA match at The O2 will be sent out starting December 8.
BTW, anyone else going? I just booked my train tickets, will arrive/depart at/from St. Pancras, which means I'll be hanging around Camden before/after the game. Anyone willing to grab a beer and talk the Knicks?
