Well I think it's finally been resolved. Sent another e-mail today explaining that it's now 10 days since I purchased. Got an e-mail back from Michael confirming that I will be refunded and "sorry this didn't work out for you". A pretty strange comment to make.

No idea why they just couldn't have made my contract active and add it into the pool.

Anyway, at least I'm no longer out of pocket, I guess.
