The customer comes last here

We were supposed to fly out of Lilongwe with SAA today and after being left in the dark until the time we were supposed to take off, airport staff informed us that the flight has been delayed indefinitely. We were just left there for 3h30 with no information. After this time the staff told us that the flight has been canceled with the next one only leaving the next afternoon. I understand this happens, planes break, but their abysmal attempt to keep their passangers informed and the assistance from ground staff is what gets me down. There is no apology or attempt from them to rectify this
