Mother's Day gift never delivered

I bought my mother a gift for Mother's Day. They said it will be delivered by 5 June 2023. From the 1st of June, they've been sending my elderly (73) mother a message every morning that delivery would be that day before 5pm. It was never delivered. She sat in her car in the parking lot for days to make sure she didn't miss them but still nothing got delivered. Called Woolworths to complain but they said my mother was called and she requested a future date delivery which was not true. This happened for 2 days. Now the Woolworth's website shows delivery was done although my mother has still not received anything. Yesterday I called again and confirmed the contact numbers and today received an email that quoted totally different numbers that I don't know. Used to be Woolworths was the elite when it came to products and delivery but now it's just one big joke.
