Woolworth Online cannot deliver fresh produce on Time

We order fresh Produce online from Woolworths. We booked our order to be delivered between 14:00 and 17:00 Friday the 3 Aug 2018 as we had an appointment 17:30. The delivery person indicated at 17:30 they were at our home, which was not helpful at all. We received a call from Woolworths Mall at Reds at 20:00 last night. His driver indicated that we weren't home which is correct but they were late and didn't deliver between the chosen time slot we have indicated. The person from Woolworths Mall at reds then indicated they would be here at 11:00 the following morning. 11 came and gone, still no food was delivered. We then phoned woolworths online to hear where is our order, they indicated it would be delivered between 14:00 and 17:00. Which is now completely unacceptable, we follow a plant based life style and we bought our weekly fresh produce so that we don't have to this saterday morning. We asked the call centre to cancel the order, no reference number was provided. Also you will only pay me back within 24 hours, which is bull****. This is food for my family, I need that money immediately
