I am not happy for that strange outcomes... Defintely I would avoid to spent more time with their games. There is nothing that can be done to change your fate so please just move on, try to find the new game for you.
Are there any other gambling games that aren't luck based? You talk as if there are some casino games that are not based on luck, I don't think there is any, correct me if I wrong, if anyone doesn't like luck based games they shouldn't be gambling at all.
I don't use stake so much because the luck chances keeps getting lower and lower so I stop using the platform, but what can we do about it? Any online casino can turn this cold all of a sudden and you will just keep losing money, it is what it is.
All OP can do is to switch online casino and abandon stake platform, it is not a crime to try other new or old casino.
