I'm having trouble understanding why you are asking such questions in this situation, despite waiting for help this much of time and after given a solution to cash out your winnings, omg you are hesitant to contact BC Game directly and prefer using a third party, refusing to schedule a video call because you don’t trust them anymore? Then once again seem to agree on video call to confirm your identity.

you should know that video calls for KYC verification are standard in these situations and most casinos require them, not just BC Game, especially with the amount of money in process is a bug sum, so the only solution to resolve your issue efficiently it's best to accept and arrange the video call if you are really the owner of the account and documents sent in first place.

But to ensure the accuracy and legality of the information on file, we would like to invite OP to participate in a video call. This will allow us to communicate directly with OP to address any potential issues or uncertainties.
