Overcharged AGAIN

Collected my second click and collect at Delcairn Centre Kloof KZN and have been overcharged both times!! First time I was told system error which I know means operator error. I am charged for 6 little chicken strips R215.64 plus vat. They cost R35.94 plus vat. This is totally unacceptable. Once is a mistake but twice is *********** customers.
