No online delivery and no refund

I placed an order on 20 Dec to be delivered on the 23 Dec in the afternoon between 2pm-5pm. At 6pm I had not feedback. The app is ******* so you can't request help. Managed to call the help center. They said they didn't dispatch because they didn't have the items? Why give the option to order then. And why no feedback? They said they could only deliver the next afternoon but I wasn't home so the order was cancelled. It is the 4th and still no refund.

I am really disappointed with your service and will definitely not use or recommend online ordering from Woolworths
