I too see similar time taken for investigation from Duelbits. Although it does not look normal but if it's necessary then a casino should have taken the time.
Not only that it is too long, it is uncalled-for and they are playing with someone's money if the person did nothing wrong. Such gambling site should be avoided. We have better casinos on this forum other than Blackjack. There are some I have not even heard complain about before, those are the gambling sites that should be used.
Thing is it already happened. The OP can not change the platform to get his money LOL.
Honestly speaking if I had Blackjack in mind to play then I would look for Blackjack. They were putting a lot of efforts one or two years back. If I remember they will giving us all free balance. Sponsor one bitcointalk event too if I am not wrong.
Disappointed to see Blackjack.fun turned this way, I used to be one of their signature participants for many months and even promote them as an affiliate they are doing good for a long time.
The signature campaign was lasted long too.
