Hi-Fi Corporation Port elizabeth False advertising and no stock , was told to collect order

i have seen that Hi Fi corp does not respond but i still want to share. i was looking to purchase a Megneto LED lantern (ironically the same one being advertised as i write this review on the top of the page) i logged into there website , created account and all. placed my order (it showed there was stock available) opted for the pay on collection option (and i'm so glad i did). everything went thru , i received an email stating my order is been attended to. about 10 min later another email saying it ready for collection. so during my lunch time i drive all the way to the store (which is a distance away, and the reason for me ordering online to ensure i don't go there for nothing) so get there inform the cashier in her to pick up my order give her the order number, she disappears into managers office for a while. then comes to tell me that they do not have stock and have been out of stock for a week , they will only get stock sometime in April. so i ask her then why does the website show there is stock (and as i type this i clicked on the add for that Magneto lantern at HiFi corp and it still shows in stock, but now my order has been cancelled) i was then told its there main office making this mistake and i must call them. This really is just bad overall service and will not be going there again.
