This is just me, but this seems like the majority of what's happening is your fault, I mean, as far as I know, BC.game doesn't allow multiple accounts even if the other accounts is inactive, what makes your issue worse is that you requested a permanent exclusion to the other 2 two account you opened before. to be honest, I don't think you'll get the entirety of the 29ETH, what you might get is your initial deposit on your current active account.

Wait for @holydarkness(a forum member who tries to help gamblers with issues with casinos), he might be able to help you at least get you your initial deposit back or if everything goes well, the entirety of your 29ETH(no premises tho).

Also, since you admit having a gambling problem, I suggest seeking professional help.
