Hi, you obviously have a problem with the casino, but please try to calm down.
If you say that the casino took money from your card without your knowledge and put you in the red, that's card misuse. It happened to me too. It's just that when making payments on the internet, hackers downloaded your details and sent the money to the casino. In that case, the fault is actually more likely to be a payment data leak. From my own experience, I recommend that you contact your bank and resolve unauthorized card payments. I got my money back from the bank.
Have the card you normally use on the internet insured against misuse and ideally only use a virtual card that is not linked to your main bank account, so you can transfer funds to it at once when you go to pay or deposit.
That's what I do.
