Digital Office Equipment interview questions

I was called for an in person interview and we set up a date and time. I showed up and was told Neil had left for the day already. They called him and let him know I was there and he apologized for forgetting my interview and promised to contact me the following day. I never heard from him or the company. Not to mention I took off from my current job over an hour away to drive to that interview. My time and money was wasted. It was very unprofessional and disappointing that people are so disrespectful.
