So, I replied that my documents were completely genuine and sent an additional set including my government issued passport, another government issued utility bill, and yet another selfie of me holding the passport this time. They still are leaning into my documents being fraudulent and refusing to pay me the winnings I made on their site, requesting that I send them a BTC address so they can refund my deposit.
With this post only, it does not make sense to prove that your document is genuine.
However I don't recommend you to post photos of your personal documents here. The same for TrustDice company because they have responsibility to keep their user documents secured and safely.
If you want to prove that your document is genuine, it must be done via a third party, a mediator if possible. I don't say anything bad about your case but assume you actually use faked document for KYC, it seems that are more unacceptable activities with your account. If it is the case, TrustDice team actually do have more evidence against your case.
