I don't know that if they have the live support with the human or not. But I just check this after create an account and then log in that they have the option of support option and after clicking it's shows something like that their support team is sleeping and they will back in the morning. I think this massage is a proof that they have support team although to final check up I have to check back it tomorrow. Right now I guessing that they have the live support system but it is not for 24/7h. Even then their discord server is quite active I think if player have any issues they can directly contact to the discord servers support team.
But whatever it is - give them a little time to improve and prepare things for the better. This casino may still be in the development stage which may take some time to perfect as its customers expect. If they can't solve it - then maybe their traffic won't be high.
