Error on online advert - Consumer Complaint for Bradlows - Head Office

I placed on order online to couches that were on sale for a weekend online. I placed an order 800011167 and the order was placed. On Monday I received an email that it was a technical error, the price is wrong. I am very disappointed with Bradlows as I was hoping to receive my couches. This happened in August 2020. We are in October, I still have not received my refund nor any communication whatsoever!!!
