I see the transaction in both blockexplorer and blockchain.info . In fact , they contains two transactions instead of one (after receiving the funds , they has been sent to another address) .
is that a case of double spending or not? I'm not familiar with this case but i have some experience with it.
@OP just wait for the funds to transfer on your wallet for 24hrs, If it still unconfirmed, Contact sportsbet.io and ask them for this issue, They are trusted and i think this is just a mistake. I've encountered this issue on bitsler and they don't have power when they release the funds.
