Ampure interview questions

Scheduled to meet with recruiting. No one showed up for the meeting. 3 minutes after interview was scheduled to start I received an email apologizing for the short notice and asking to reschedule later that day. I replied that was fine. Heard nothing all day. Finally at the end of the day I received an email asking for me to reschedule next week. I said I was open to that. Heard nothing. Followed up on Monday and didn't receive a reply. Emailed on Tuesday (after still no reply) that I was withdrawing from the process as the company wouldn't be a fit. If I was a "backup candidate" fine...but respect my time. Reschedule BEFORE the interview is scheduled to start and do me the courtesy of replying.
