“ I most recently found out that we apparently are giving a 10% cut to the Secret Organisation. It seems like Puppey had decided there is a 10% cut and that we should simply accept that fact.”
I cannot make any comments without seeing your contract, but this seems sketchy to me; along with a whole array of other things Secret have done. What does your contract, specifically, say regarding the prize money? If there is no mention of the 10% fee to Secret, and no other contract was made (verbal or written), then you should seek to recuperate the missing 10%.
