RUDE CUSTOMER SERVICE(ALLAN), FALSE ADVERTISING!!!!!

I drove 110km to go buy a office chair. Got at Montague Gardens branch. Two of the chairs was on display and when I want to purchase it was told to me no stock. How can a Company advertise goods on-line and in there shop if there is no stock. THIS FALSE ADVERTISING!!!! Asked to speak to manager Allan was called with a very rude and ****y told me do what you want and display chair not for SALE!!! WOW!!!! GREAT WAY TO TREAT CUSTOMERS AS THE CUSTOMERS AROUND ME LEFT THE SHOP ALSO!!!! GET YOUR HOUSE IN ORDER AND WELL DONE FOR THE **** SERVICE!!!
