Bad customer service

I booked a flight to Bulawayo for 22 Dec 2019. My gosh what a terrible experience i had. the flight was supposed to depart @ 2pm upon check-in i was advised that it has been delayed to 2:40pm. Surprisingly the flight only departed after 5pm. No one bothered to explain to us why we were delayed. As if that wasn't enough when we arrived in Bulawayo they told us our luggage was left behind it would arrive the following day. Mind you we were going to a church conference we didn't have any clothes except what we were wearing on that day. I was with my 8 months old baby. All her necessities were left behind. I had to ask around from those who had babies for nappies.The next day we had to spend almost R1000 just to go to the airport twice to check if our luggage has arrived because no-one bothered to communicate to us whether our luggage had arrived or not.
