Stolen account

Greetings.For the second time some player stole my account and he is still trying to get there. Please do something about it.

When a player wants to change my password through my account name, it automatically turns my email into a completely different and unknown email.

Enable 2FA and he shouldn't be able to do much then.
Consider not sharing account info with others in the future.

I had 2FA turned on. He asks asking for Support on Email. I have no clue
