Well, there is nothing that BC.Game support will do in this regard other than the instruction/advice they've given to him because they will have to be thorough in satisfying the regulatory aspect of the KYC to get exonerated on their part. If it were to be another situation, I would have reacted differently and taken the OP more seriously but this is a self-caused issue. You want to withdraw but you do not have all the requirements to withdraw. Since that is the issue and you already know it, why not get it fixed? It is as simple as that instead of crying foul. No one will support you on that. That is why it is even better that you complete the KYC in the beginning to avoid issues like this.

Another thing I do these days is to make sure that I use a non-expiring ID to verify my accounts to avoid future issues. Do you know why? Some companies have now started copying themselves with the habit of disturbing their customers over again to provide another passport, for example, on the expiry date of the former one provided. In this situation, issues like the one here may still arise.
