Cintas Sales Representative interview questions

I applied a couple of weeks ago for several positions & your company can't even call me to chat about it or possibly set up a interview. I had a interview with one of your manager's at the Maywood IL location but the day of interview he called me & cancelled saying he had a emergency in the field but would call back to reschedule interview. well that never happened & even when I called him to leave a message he didn't return my call. doesn't seem very uprofessional to do something like this? Have a wonderful day.
