How to report players in an FFA 4-Player Chess Game

in these FFA 4-Player Chess games, there are those who are already partners from the start of the game and would support each other to ensure that they win their games, which is clearly prejudicial to their opponents who are simply solo players. Their acts of helping each other out by not eating their other partner's pieces and by assisting them in gaining points or by acquiring a checkmate in order to reach first or second place, became so evident especially at the late game where only 3 players are left at the board. 
 i was able to follow through their next games and yes, those two players were still together in one same board, and still secretly helping each other out to win the game. Someone pls address this, its my second time now to encounter such

these guys left each others queens hanging w/o bothering to take it when it was completely free. they co-ordinated their attacks as you can see if you check the game out. and when i called them out one of them responds saying that cross-teaming was allowed bc its not their in the manual.
