So Section 8 has been so weird with my inspection

I live in New Hampshire and I got the state version My inspection was in March. They called and cancelled cause the inspector was sick. Fair enough.

The next inspection comes around. I get no notification or anything like last time . So I call them it got rescheduled to April . They never told me this. I got a "sorry for the confusion" at least she was honest?

Why didn't they tell me about the change? Is there anyway to know for sure for next time?
