Worst online shopping experience from such an exclusive retail brand

I purchased from Woolworths online on the 10th April 2022. Due to the flooding the delivery did not take place. Since then the delivery has not taken place. I purchased items that was for Easter for children and Easter has long passed. I have since been calling Woolworths to get a refund and each time I call I get no refund or feedback. I called on the 01st May 2022 requesting a refund again and have since not received it. I called the 13th May 2022 to follow up and was told it would be escalated and I will get a call back and since no feedback. My order number is o***. Can I please get my refund. I have had the worst online shopping experience ever. Wont recommend people using their online shopping services.
