Constant Desync every Mut game

 I was cheated out of an ultimate team championship win which is held through the game by someone who performed a Desync with only a couple sec left in the game. I ended up getting the loss and he won the prize which I think is not fair. I would like something did about this or someone to reach out. I have all the proof and the players name who is scamming people and taking money from EA in game tournaments.
