Disconnected after conceding

I was playing and my game disconnected immediately after my opponent scored. This happened twice today in Division Rivals. Coincidence?

Is this a glitch in the game? Or did my opponent somehow cheat?

The game never disconnects after I score. EA has made it impossible to report suspected cheating. Seems like they are protecting their revenue source.

With this loss, I have just been relegated back to Division 7. This game is so frustrating.
