You cannot join another NPC sorority, no matter how unfairly you feel you've been treated. The rules apply to all members of NPC sororities. There are no extenuating circumstances that will change this rule for anyone.

Your best option at this point is to remain in good standing with your sorority and become an active alumna. There's always the possibility that a chapter won't be interested in affiliating transfer sisters. Perhaps you could get to know the members better and they could vote again later, but if you've annoyed them, reported them, etc., that ship may have sailed. At this point, avoid aggravating your sorority further. This isn't a situation that can be remedied by making yourself appear less sisterly. Don't burn any more bridges.

As someone who transferred and affiliated, I think it is wise to reach out to the new chapter ahead of time. Be friendly, sisterly, enthusiastic, and see what kind of vibe you get back. I think this is a better strategy than making contact once you've already transferred, because you can't assume all chapters will be equally welcoming to transfer sisters. Frankly, if they're not, forcing the issue probably won't result in a happy experience anyway.
