Shocking

This has been the most shocking, and frustrating experience. It was my first and last order from the Woolies Dash. I ordered something small and the completely changed my order. They got it wrong and then when I called I gave the services my details and the app changed my order but I luckily have screenshots and emails. I have been now sitting after a 2 hour wait for the wrong order for another hour for them to fix this. All I want is a refund so I can delete this app!
