Answer technical support:

""BET tokens were replaced with the new ones due to a hack, so was their contract address. Etherscan shows that tokens were sent from old address, which means you've sent old tokens, which are no longer supported. Unfortunately, there's nothing we could do about this as once transaction was completed, it is now a part of the blockchain.
But you may contact DAO Casino so they could possibly help you.

Don't hesitate to get back to us if you require any other assistance.""

Help please understand the question.
