False advertising

I went into Makro Polokwane on the morning of saturday the 19th March 2016.I went to a shelf were they put champagne and they had Moet and Chandon Nectar with a price tag of R45.95 a bottle.I asked one of the employees in the store to help me load the bottles in the trolley.The manager on duty came and said the price was not correct and they told me head office made a mistake.I feel that the retailer owes me an apology as that is false advertising.I cant go around in the store if the price put onthe shelfis the right price on all items in the store.
