Do the tickets come through the post or print off ?
Post. Ring the number per the link on post #1.
Took ages. Press one for FA Cup tickets, it'll then tell you there aren't any..no, you don't say

....but don't hang up, wait, then the music starts and the annoying wumman eventually tells you how far down the que you are.
Took me about 15 minutes to get through.
I insisted on a payment reference and customer number JUST in case the tickets don't turn up.
You've got until 2pm tomozo, subject to availabilty apparently.
