No doubt this wasn't done intentionally (I hope). It's still a good idea to call Panhellenic and figure out what went wrong so they can prevent it from happening in the future.
I learned something new in this thread. With NPC, you don't want the call. With NPHC, you do want the call. It's the letter in the mail you don't want! What happened to this young lady is unfortunate. You've brought it to the attention of the Greek Life office that more precautions should be taken.
