Macrosive interview questions

The HR contacted me via Indeed and sent an email with the interview scheduled, on the time of interview when I joined there was no response I waited for 10 minutes and contacted on the number mentioned in the mail, there was no response, I called 3 times but still there was no use. I waited for about one hour in that interview link but no one admitted me into it. Just want to say to the team that please understand the situations of the interviewees, we active job seekers everytime when we get an interview call we look into it with great hope so if the interview is cancelled the least they could do was to inform.Very bad experience!!!
