I just tested it on my account and I was able to disable my 2FA with the email code. What error message are you getting?
Also, can you open a support ticket on Discord? We'll be able to all collaborate and work faster on it there than here. If you can't, no worries.
Can you link to the server/messages on Discord? We would need to see them and verify them.
But in general, for stuff happening outside of the P&W Discord Server, we have no ability to moderate the content. That falls upon the owners/moderators of that server, along with Discord's Trust & Safety Team.
