That's just down right wrong and I'm sorry for your having to go through such craziness. My statement to you is simply this - I would still report the incident to the campus police and even the local police. I would've even taking pictures of the vandalism and kept then just in case the situation gets worse. However, I still wouldn't let other deviant beings stop you from sporting your nalia. I would replace the tag with another and continue to represent my sorority with pride.
