False adverti*****t

I went to incredible connection clearwater to purchase the Xbox One deal which was advertised for R3999. When I got there I was told that they are out of stock, I then asked if there is an alternative store that I can go to, to purchase this deal and without even checking the stock availability on their system I was told that the whole country does not have stock. The pamphlet clearly says prices valid from 16 - 24 December 2015 and does not say limited stock available or that deals will be subject to stock availability. Why do you bother advertising something if you can't cater for the demand
