Canceling a deposit at an online casino.

Hello, do I understand correctly that you deposit and after the deposit is processed and shown as successful, you have the option to cancel it while you wait for it to arrive in your player account? Or would the deposit also be successful in your casino account and then you would cancel and play with the money? I know there is such a possibility, but only in the sense that when I deposit, I can only cancel the deposit immediately and therefore it won't take the money away from me but also I won't get it into the casino account. But if you want to somehow trick the casino into crediting your player account and playing for free, I don't recommend it. 

Thanks. I was just curius that the bank is giving you that choice!

In my opinion, that depends on the casino and the banking system; however, doing something may "flag" you in the casino system—similarly to anyone else who opted for chargebacks—so one has to be ready to face the consequences.
