Shocking service from Woolworths

On Monday morning 4th January 2021 I ordered groceries on line using their new Woolies Dash app. I was given a time slot of between 2 and 5pm on Tuesday 5th Jan. for delivery. I had to pay for the goods in advance but nothing was delivered, I phoned on Wednesday 6th Jan and was told the goods would be delivered between 10 and 1pm. Once again no delivery was received. I phoned again at 2.30pm to query non delivery and I was told they would call me back. This has not happened. Woolworths were very quick to take my money but seem to be reluctant to deliver the paid for items. I would appreciate if a senior person at Woolworths would call me 082****067 to resolve this impossible situation.
