Account hacked

Yeah, another hacked account post. I got hacked seemingly outta nowhere, I sent in a ticket, and someone even replied for a while! Though, just when I was ready for 'em to turn off 2FA, they were gone, and stopped replying! I'm scared to send in another request, as it's possible that it'd trip that spam filter it mentioned...

If any of you happen to have any ideas, please let me know! It's rather urgent.
