Disgusted with Woolworths online

I placed an online order on 29 March 2021 for delivery on Sunday 4 April 2021 between 10am and 1pm. I get a call from Woolies on Sunday at 9h15 informing me that only 1 out of the 4 items that I have ordered is available. I was told that because it is Easter weekend, the items have been sold out. If I placed the order on the 29th already, then these items should have been put away in a safe place for my delivery - why only on the day of delivery do they see if they have the items in the store. I needed those items for lunch that day and had to quickly rush around to the store trying to get the items that were not delivered. And now that the order is cancelled - I have to wait a few days for my refund. This is unacceptable!!!! I want my refund paid back to me immediately. I will never order anything online with Woolworths again. I am so disgusted in their service delivery.
