Woolworths Dash is the Worst

Woolworths Dash App is the worst delivery service I have ever come across. Every time I order from them there is an issue. I hardly ever receive my full order, they make their own substitutes which I never authorized and they don't bother to inform me as a customer that certain items are out of stock. Their "choose a substitute" option is a joke, when you click on it, it says there are no suitable substitutes available which leaves with no option but to hope that you will get your first choice. What a waste of time ... I would never recommend this App to anyone.
