Treated unfairly at Killarney Mall

Went there at the store to withdraw Sassa for elderly people today,when I got to the till after waiting in a queue for such a long time the cashier told me she didn't have money and asked the supervisor to assist, a coloured old lady Antoinette told me to wait in another long queue as the other tills didn't have money for Sassa,was so disappointed with this as there was another white old lady that was given money at the very same till I was from and no any other race except a black person would be !!!no any other person would have tolerated and would be told to stand in another queue after waiting for so long,so dissatisfied after being treated that way at Pic n Pay Killarney Mall ₩₩₩
