Visual Image Systems interview questions

First was called and offer to interview that next week - I took PTO for Tuesday of the following week as I lived two hours away from the company site and had to take off work to drive and interview. Interviewing manager then canceled last-minute on that Tuesday, asked "can you do it tomorrow?" and I said, it would have to be Thursday. Took PTO on Thursday as well, drove to interview, it lasted an hour, he told me I would hear back either that night or the next day. More than a week later, I haven't heard back. Worst interview experience of my life. Incredibly rude and unprofessional behavior
