incorrectly priced item

i am really shocked and i never thought that thi would be the service i would get from a company that i admired i was at your store at carlton centre to buy a gift which was an iron and kettle on the shelf i found a russell hobbs glass kettle and the prices was R179.00 i took the kettle and russel hobbs iron but when i got to the till it scanned 389.00 i asked to speak to the supervisor her name is grace she came and told me straight that i will not be sold the kettle because the barcodes are not the same and as a customer i am entitled to pay the price that i see and i do not work at the store i dont know anything about barcodes i am not happy at all
