Damn, you are really persistent. If I was at your place, I would just give up and keep playing until I lose all the crypto in my account.
The only thing you could do is to keep waiting for a response from BC Game customer support. Patience is key. Maybe you should also post "negative" reviews about BC Game here and there, the casinos usually hate this and BC Game customer support might suddenly reply to your emails and try to solve the issue. This is yet another typical "gambler can't withdraw big balance due to failed KYC" story. I wonder what the casinos would use as an excuse to deny withdrawals, if KYC gets removed as a requirement some day.
I know, right? If I were in OP's situation, I probably would have given up and gotten tired of following up. It's almost like the casino just wants OP to keep playing until their balance runs out,
and then the problem is solved—that's what the support team seems to want, hehehe.
But seriously, that's such a headache and so stressful, especially considering how much that amount is worth in our country's currency.
The support is taking so long to respond, which also makes me suspicious, unless they're intentionally doing it until OP gives up.
