I am writing to file a complaint regarding a bad experience in a tournament

I was doing my fut champs and was going 7-7 and was on my last game to get 8-7 when I was 2-0 up in the first like 10 mins (game time) I got kicked out because of technical issues bearing in mind I got through all them games without a problem and it counted. It’s a bunch of **bleep** and this game is honestly the most rigged piece of **bleep** game I’ve ever played. Why I keep playing it I’ll never know but Jesus Christ man
