Constant Disconnection from servers with no Wi-Fi issues.

When playing in any game mode that is online on this game there is always a small chance of my game crashing. But it has gone further than that this year. I havent been able to properly win many games against what I think is a tough opponent because either they are a hacker and disconnect me from the game or ea kicks me off their servers. I was just playing the cornerstones knockout tournament and then I vs someone who happened to disconnect me from the game when I got a free kick, I wasnt even winning but still only trailing by 1 goal and this "humble hacker" as some would call him kicks me from the game. And even before that I noticed that my players were playing at least 50% worse than before in a previous match. I have come here as I do not know what to do anymore and how to contact ea to get this over turned somehow because it is very frustrating to work hard all day and try to have some fun playing this game but it is ruined by people who decide to hack and abuse broken disconnecting ability.
