More than 48 hours has been passed and I'm still waiting for the reply of their email support. Maybe the team is having some vacations, otherwise they are busy with other important things. A live support system is really helpful in case of instant enquiry. Blackjack.fun team need to bring this feature. I'm also expecting to see the update of their TOS page. The information are messed up now.
@sujonali1819, I can see you are highly connected with Blackjack team. Do you have any information about their gambling license?
