It's not me, though I did have the same wagers elsewhere and both stood. However they're not denying that it happened, I'm sure you have lines of communication with Justin if you want the details.
BetMania claimed (through SBR) that they can cancel any wager, so long as they do it before post.
Had it been me I would have gone to somewhere that they sponsor (i.e. here) rather than SBR, but it's an important debate on when a book can/can't cancel.
I only play at 2 offshores these days, don't trust the vast majority.
