Email was hacked, Need Help!

[ryanfischer1]

My email account was recently hacked into, I changed my password and added 2FA, but the person is still able to access my emails.  How can I force them to log out of my account?  That way when they have to log back in it should be protected by the new password and 2FA I enabled.

I really need help with how to do this, there is no option on my account to log it out of all devices and when I called customer support the automated response doesn't have an option to address my problem
