My coins have just disappeared from my ultimate team account

I had 1.2m taken off me last week for same, this company goes out of its way to destroy people who don't spend money on this dreadful game, I had roughly 800k saved made 400k on transfer market, I contacted ea regarding my coins they said I had been buying and selling coins didn't give any other reason and closed my case didn't even let me explain that I did nothing wrong they don't care
