Bad service from Makro.

While doing our shopping at Makro we had bought quite a lot of items including a Lindt special of 6 x 38g bars for 60 Rand as advertised on a board where the chocolates were. After scanning all the items the price of the Lindt chocolates scanned at R13.95 not at the price of the discounted price. A cashier went to check the price and would not allow me to follow her, when she returned to the pay counter the marked board had disappeared so the discounted price was not allowed. We left the Makro store in Meadowdale after no help from the manager leaving all the items that were already scanned on the counter and left the store out of principle. Very bad service and not the first time this has happened from Makro.
