Hi fi corp

Good day i would like to lodge a complaint on hi fi corp. on their brosure dated 28 Dec 2020 - 31 Jan 2021 they advertise a laptop notebook HP14 item no ***0 for R2999.00 online .when you try to purchase it the price goes up to R12 999.00. this in my view is balatant misleading advertising to lure customers to the shop and then sell the item at inflated prices.
