No knowlege of their jobs

Basic complaint. <br> Waiting as everyone else would. Go down to board. And see Flight SA1510 IS DELAYED. <br> <br> NO mention of this on the PA system. No announcement. <br> <br> Asked politely at gate for information. And the staff at both gates. 1 and 2. Just pointed me to a screen and said they didn't know anything. <br> <br> They showed no interest what so ever to help or give any advise...
