Hi There. I purchased a dress online for $220 from an Australian Retailer (Based in NSW). My payment went through and the money was deducted out of my account. A few hours later, the seller had emailed me saying that they had advertised the dress for an incorrect amount on their site and that the dress is actually $420. They went on to say they had refundedt the money and it would take 3 days for the refund to reach my account without even asking me first or offering me other options. They also advised that if I wanted the dress, I would now have to repurchase it for $420? What are my Australian Consumer Law rights? Has the company breached anything? Are they still obliged to send me the dress for the amount I originally purchased it for?
