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.

Probably at the start, he had no problem, but when he started winning, that's when the problem arose. He couldn't cancel his withdrawal because he wanted to enjoy his winnings, but he was required to complete different verification steps until he got tired and maybe just forget about his money. The problem is he didn't start with KYC verification, so a scammy casino can use that against him.
And there's this multi-accounting accusation that is very common for scammy sites. They'll tell you that you are violating this rule, and you can't counter it as they hold the information that supposedly links you to certain accounts. I mean, how can you contest that to prove you are not cheating if they have already made a conclusion?
I understand it. That`s why i`m talking about "last chance". I think here we can`t find the truth. The OP will say that it is honest win, the casino will tell us(if we`ll find their representative) that the OP is cheater.
It is situation when the OP mistaken with the casino choice. Nobody can help him if he telling the truth. The only positive moment is that we have to remember these casinos before register.
