Power Direct interview questions

I spoke with a HR Representative who basically told me the company would call me back if there was an opening for any departments. Since I was employed at Power Direct before, I was eagerly waiting for that call, but none came. I was disappointed with the interview process because the staff at Power Direct know me, and they know I am a hard worker. I felt that I was pushed away and that they were very unprofessional in letting me know if I would be employable or if they didn't want to hire me back.
