Multiple on site interviews with panel of management staff who explained the job and hiring process in detail. And answered any questions that I had about job. Great Communication whole process

I was asked to schedule an interview last Thursday. We set it up for the following Friday, and I was told that I would receive an email with confirmation and directions. I never received it, so Wednesday, I called and left a voicemail to confirm my email address. I never heard back, so called again today (Thursday, day before), and had to leave another message. She finally returned my call this afternoon, and left a voicemail saying that the interview was canceled because they decided to offer the job to an internal candidate. 1. I took off work for this interview that never happened. 2. I was never called letting me know it was canceled. So I'm wondering, had I not called, would they have called me? I would've driven down there and shown up for nothing. It was very unprofessional the way it was handled and I'm very disappointed. I now have an afternoon off work that I don't need. I asked a few coworkers to use them as references and a midwife wrote me a recommendation letter. I prepared a lot for this.... I don't think I will apply for CCF again.
