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.
Uhh... if you bother to read... actually we're currently working on it. So, maybe we it'll be better if all of us remain in our seat until things become more clear.
OP, following our talk in PM and the file you sent me, I relayed it to my contact. If I may repeat what I wrote back to you on PM, respecting your privacy as much as I can, I didn't read the whole document, only glancing at it to see if it contains address.
My contact [who read the document thoroughly] say that they don't think the address is a "real" address, in sense of your home address, and rather some kind of P.O. Box? They're currenly inquiring to the KYC department, but they don't think it'll work. Is there other bank statement that says something like, "221B Baker Street, London"?
Or perhaps someone home can send you a scanned document of your most recent statement? Electric bill, water? Bank printed-statement?
