Employer reschedules interview and is still late

As you can see in the screenshots, I had a meeting scheduled for 9:30. I follow up with the employer and not even 15 minutes before he asks if I can wait an additional half an hour to the interview. Once again I message him at 10:00am to no receive a response until 10:15, my first impression with this employer is waiting 45 minutes for an interview - obviously I left. Am I in the wrong ?
