Master's student applying for an internship

On May 29th I had an interview with a company that claimed to have great interest in my profile. I suggested a video call interview and they said they preferred it in person. I had just arrived at the parking lot (it's about a 2-hour round trip by car and I arrived with 1 hour and 30 minutes to spare) when they called me saying the manager was sick and that they were rescheduling my interview to today, the 5th. Today I went again and they cancelled the interview again just moments before arriving, telling me this.

Have I been treated badly, or is this normal in the professional world? Just asking out of curiosity, as I don't have much experience.
