Builders Dumb Website

First tried to get an item which had stock on your website, in store it was damaged stock, I was told new stock coming Friday or Saturday, I go home and I placed an online order to collect, got an sms saying its ready. I go to the store the next day only to hear "sorry no stock" , what bulldust is that?

Does your website not communicate with the store to ensure products are ready for pick up? Why tell me to come pick up my items when you don't have it?
