Phone up the ticket office.
I put my 2 tickets (adult and child, front row of the WSU) on the exchange this morning. I kept checking, using a third account, and they NEVER appeared online as available. Like you, I'd have assumed there was not a pair to be had.
At some point this afternoon they then showed as having been re-sold. So they either did appear online and sold within, literally, a minute or two, or they never appeared online and were sold via the ticket office. I'm pretty sure it was the latter.
Or alternatively reply to someone's pm offering the exact tickets wanted, in a prime location.
