To bad that you realize your mistake made after stake putting some harsh decisions on both of the accounts handle by you and your husband. Then I guess they have the right to take action regarding on the situation. So maybe next time much better if you read the TOS before taking action so that you will not say that you didn't know that you already violate the rules of the casino since they will not honor that reasoning since its bad mistake for a user which can be avoided if both of you just try to spend some time to know their rules.

Just reach up their support and ask politely for possible refund so you can move on to other casino if you or your husband still want to gamble on online casino. Then learn from what happen here so you will not do the same mistake on other casino.
