Mountain Valley Express interview questions

I had a video interview with their recruiter, who told me I was overqualified for the position I had applied for, but that they had another open position that would be more on my level. She said she would set up an interview with the hiring manager and gave me the date and time. After we got off the call, I never received an invitation or information on how to join the interview with the hiring manager, which I was under the impression was already on the books since we had agreed on a date and time. Follow up emails to the recruiter were first answered vaguely that we needed to reschedule, then were ignored completely.
