1. You're not the player that win 12 btc on stake.
2. That's just a bet ID, not a proof of withdrawal.
3. There's no proof of chat that the player were ignored by stake.
4. Fuck off.
It's ironic this person tagged as a scammer by quite a few reputable people is claiming such acts by others, they really have not provided a single shred of evidence - a screenshot of a random chat doesn't prove anything. While nobody should be above suspicion of wrong doing, Stake really has little reason to scam - people flock to their games every day and the "house" is already engineered get to skim a small commission off most bets. They don't need to scam because they own what basically amounts to a money printing machine, at this point they have done most of the development groundwork so little extra expense there, staffing costs are minimal and the advertising budget can be very flexible. What you usually find when random strangers come out and accuse a big gaming site of abuse, it is usually someone who has deposited money and lost it all. They want to try damaging the reputation as a way of revenge and hurting them back.
