Took all coins From me

Hello, yesterday Ea took all my 650k coins From me because of suspicious of illegal activity such as buying from 3rd parties and transferring coins from 1 acc to another. That’s completely unacceptable and untrue from such as big multibillion to make a mistake such as that. I send them a reply and they said that their actions was correct! I saw so many guys rn getting banned or got taken coins from them but I want to ask Ea or anyone: what’s illegal to buy a player and second after sell for big price and profit but it’s LEGAL for YouTubers to promote coin buy and transferring coins and promote trading discord group? I know that I won’t get a reply from them but this is a big problem and so unprofessional by that big company!
