Try to hit the chatbox and let the admin there look over your case, Admin is more active on the chatbox since they moderate it most of the time, unlike their email support. @Oth3rion is the active admin there so make sure you mention him on the chat so that he can easily notice your concern.

Can I know if the admin has already looked into your case or not? Share some of your concern details here so that we might help you in case we have already encountered that issue. Blackjack.fun support is very professional and they will surely resolve it ASAP.
