Cabin crew not ensuring safety of passengers

I flew with FlySafair this past week. Because of the COVID regulations they obviously didn't serve anything. So I thought they would have the time and opportunity to ensure our safety on board. I hardly saw the cabin crew. They were all somewhere at the back - no checking on the passangers at all. Two rows to the front was a young child - no face mask, jumping around in his seat, blowing spit everywhere. That is not okay, specially not during this time. The crew had ampul time to make sure this doesn't happen. I don't think i will fly with this airline anytime soon again.
