Denied entrance

Absolutely horrible service at Montclair mall where my dad (who is a senior citizen)and I were turned away at the door the lady who turned us away claimed the stoor closes at 17:00 while the sign said 18:00, we were at the door at 17:20, she refused yo look at the sign to confirm the time of closure, her name is Lindiwe, I expect better from Ackermans
