The last chance is to cancel the withdrawal and repeat it. I don`t think that it will help, but i don`t think that there are some reasons, why the OP can`t get his money. And iif the OP has no problems with casinos - why he has chosen such two of them? Or if he has problems with casinos - may be we don`t know something?
Attempting to withdraw again will not work since the OP has an ongoing investigation on his account due to possible multiple account as stated on the OP. Both casino has some reason to hold OP money, either true or not it’s very hard to win against mediocre casino that doesn’t have representative here.
If it's true, obviously we can't do anything about it and we might even get accused for doing a violation but if not, we can only hope that our money will still be returned to us. There is still a chance even if we think they are very shady, as I've seen similar cases like this in the past.
It's really funny that they are still afraid that their reputation will get ruined when in fact it was already like that, so they just settle the damage that they have dealt mostly to the complainants on this forum. They know that Bitcointalk is the largest Bitcoin/cryptocurrency forum, so they are giving a respect to it, in the hopes that people are going to trust them but personally I will never turn back to them for any reason. I mean there are people who do change their mind on seeing some big freebies.
There are lots of options for us in this crypto space; so we never to continue on any shady places for any reasons. Once we get any red flag then we need to be cautious and must start switching to safe places to secure our funds.
