No action from Woolies following incorrect delivery

On 22 June 2025 I bought a jacket on a Woolworths sale via the Woolies app. To my surprise, a white shirt in a massively too big size for me, arrived. I returned it to the store, who told me I had to contact Woolies online services for collection and refund. Almost 30 minutes in store wasted. I have since exchanged multiple emails with Woolworths and I keep being referred from warehouse to the Woolies fulfillment team, but yet no outcome. Apart from a terribly frustrating app, I am now dealing with the worst customer service imaginable. Do you not want to give me a refund for your error, Woolies?
