My other account was banned

After a long time, I wanted to enter FC25. I already use my ea account only to play FC25 but I saw that my ea account was banned and I was told that I violated the user agreement or sales agreement but I was already using the account very little and was unplayable for a while.  Most likely my account was stolen and my account was banned. Please help me. I barely bought the game and it's really sad that my account for which I paid so much money was banned. All I did on the account was play FC. This is really ridiculous
