Always happens to me. 

Match was supposed to be over on 92 minutes yet my opponent was able to grab a winner on 97 minutes. I've had loads of offside goals count against me.

I've had penalties given when I've headed the ball away yet the replay shows my player sliding in with a challenge. 

You won't get any answers from EA, they'll tell you they'll look into it yet by the time you hear anything the next fifa will be out.
