2FA set up without me, locked out of my account,, gross bot activity in the last 24 hours.

Someone hacked my account and set up 2FA without me. Now I'm locked out of my account.

I changed the password but can't log in without the 2FA key. I submitted a ticket yesterday but haven't gotten anything but auto-suggestions as a response. I have alerts turned on so I am getting post replies in my email that suggests bot activity that I am really uncomfortable with and don't want associated with me.

Account is u/ichigoli please help.
