The advice is actually right, you need some serious help their buddy. Asking for a refund after losing is never going to happen if it's an outright activity that you did there.
There's really a serious matter on your case OP and those are signs and you have to admit it and don't put the blame to any casino where you voluntarily deposit your money and gambled with it.
True, it is someones willingness to make out some deposit and you havent been forced to do so even though Stake does have some fault on this one since they do still let those players who had
been asking for some exclusion but actually this kind of feature is useless if that player does have that severe gambling addiction on which they would really be finding
ways for them to play no matter what and i never heard that casino do make out some refund on someone who do losses into their platform.
This thing is impossible.
