Will I be black balled?

I'm at a dilemia.Well a few years ago I applied, and got accepted for memberhsip into a welll known african Amercican Sorority.After i got accepted I never went through with joining, because I just didn't like how I was being treated and plus I was going through alot of stuff personally.However, I've became acquainted with a few member's of a different NPHC, sorority and they are fabolous.They are friendly, encouraging, respectful, and courteous.I enjoy them alot.I have pondered the thought of joing this organization, but I 'm having second thoughts because i don't know how the people willa ct towards me if anyone finds out that I applied for memberhsip for a different organization.Should I or Shouldn't I ? Please hel[
