I am not trying to defend the cardroom but they did not give your money away. You got hacked to do whatever reason it may be ..weak password ,shared computer, virus hack or none of the above.
There is a slight chance that you will get your money back because withdrawals or login into your account can only happen from a trusted
. Even if someone were to hack your login they couldn't get in with another device because of the two factor authentication method.
I am not sure what happened here but your chances are very very slim.
