Overcharging, taking advantage

Tops at Spar Doreen road Ruimsig. Almost double charging on some liquor products. Labeled and barcoded at one price and when you get to the till, the price is almost double! When comparing with other Tops outlets, prices are indeed double than any other outlet!? Is it because it is situated in a "fancy" area? Are people not checking their till slips there and the store is simply getting away with this? Management not taking responsibility and refuses to charge whst the barcode label states. I Will ensure this store will pay for it in the long run. What goes around, comes around.
