AM Pierce & Associates interview questions

I was contacted by an AM Pierce recruiter via email asking if I would be interested in the position. I stated that I was indeed interested and she then suggested a date and time for the interview. I replied back that the day and time would work for me; in addition, I also provided the best number to reach me at. When the interview time arrived, no one contacted me. I even emailed the recruiter asking was the interview cancelled and never got a reply. This was beyond unprofessional and the company should be aware of how their recruiters treat applicants.
