They actually asked you to accept their TOS and you not only deliberately broke it, but also deceived the site by using a VPN. If they asked you if you can afford to gamble you would have lied too.
To be fair, I bet there are many, many people (including members of this forum) who use a VPN in order to get around restrictions. In OP's case, though I don't think it was a good move because he's a self-admitted problem gambler, I don't think what he did was so wrong that I'd condemn him for it. That's just me, however. You can condemn away.
If I'm understanding his post correctly, he lost a lot of money on stake.com but didn't get scammed by them, just ignored by their customer service department--which could eventually be resolved in time, right? If that's the case, no matter how sympathetic I feel for OP and his gambling problem, it isn't any casino's responsibility to prevent you from doing harm to yourself, at least not legally as far as I know. That's true for real-life casinos, and you'd better believe it's true for online ones as well. They don't give a shit that you lost big time, and in fact I'm sure if they were to speak the truth they'd say they were happy about it.
OP, no one aside from family is ever going to coddle you in this world, and I can't even say you're lucky if your family even does that since it doesn't prepare you for the harsh realities of life. This money that you lost
is the warning that you wanted from stake.com. It's an expensive warning and lesson, no doubt, but make sure you heed it and get help with your gambling problem. Sounds like it's only going to get worse if it doesn't get better soon.
