Woolworths make empty promises and disappoint customers

I purchased from Woolworths online store Lindt chocolate biscuits and pretzels and some other lindt chocolates because they had them on sale for a really good price. These were going to be given as party favors. A lady called me on the day they were supposed to be delivered 28 July and says there is no stock. I tell her I’m disappointed this was supposed to be gifts and she just says there’s nothing she can do and apologizes to me. They supposed to refund the card I paid with. I have since emailed Woolworths twice regarding my refund.. 28th July my order was canceled by Woolworths today is 1 September I have still not received my money back!!! How is that for service???
