First round telephone interview was a positive experience. Second round video interview was pleasant, said they would take a week to let me know how i got on. But they never got back to me

I applied for the Supply Chain Coordinator (6 month FTC) role and received an interview invitation email on the same day. After that, I did confirm my availability for a phone interview at 11 a.m. on Mar 11, 2022. However, at 10.30 on Mar 11, I received an email I telling that the interviewer had an urgent personal appointment and asked me to confirm my availability again to reschedule. After I did it, I never heard back from the company again, which was really strange. I did send a follow up email asking for the rescheduled interview but I haven't received any reply from them ever since.
