Xbot glitch

I have reported this player on xbox as he is on the same platform as me.. I was doing the future league tournament trying to get either 4 wins or 4 goals to get the 2nd evo. I came across a player. The same kicked off amd within 1 minute he left and it gave him a 3-1 win. I certainly didnt score the game was literally 1minite in from start of first half. Anyways he was then put through to the next round his EA name is [removed] same as his xbox. I can not report through the app as I can not find what i need to report him
