Try asking some sisters to hang out. Ask them if they have time to grab lunch or do something on campus. Try going over to the house and just hang out with them. You get what you give to your sorority. The more time and effort you put into it, the more time and effort you will get from other people. Try going to as many events as you can. They should tell you with advance when all the mixers/philanthropy events are so you will minimize scheduling conflicts. Sororities aren't 'paying for your sisters' as you see, you have to put some effort in as you would any other relationship with a friend.
