Want to report many players using the glitch !

Hi I want to report many players that are using a glitch on ultimate team EVENTS to leave the match when they score 1 goal, the pause the game , switch account , wait couple seconds and then the match is over giving them the victory and i feel this unfair and disrespectful in the FC community, i want make them get banned to see if they learn to don’t do this . How Can i report this players , thanks !
