First, congratulations to the trolls who have bank accounts that charge no fees because they're very wealthy or whatever other reason. Second, a "please get lost" to the other trolls bashing the OP because he was playing at whatever casino he wanted to play at.
Now let's get back to the problem in question: the OP's transaction disappeared from blockchain.info, and he hasn't received his Bitcoins. Did they return to the casino's address they were sent from? With the transaction information gone, how do we know for sure what happened to the Bitcoins?
