Time was scheduled for interview but nobody showed up to the meeting. Waited for over an hour. Also sent a follow up email to hiring manager but no response. Role is still up months later

First got an initial email to tell me about the role, the salary, how my CV was great and wanting to get to know me. I responded promptly with questions, when we could chat. The hiring manager never responded. I received an automated email that I was not chosen. There must be some miscommunication but I wrote another email to get an answer and still nothing.
