In a case where a supplier promises a product through their advertisements (quality of product) but does not include it within the contract and a customer was to sign this contract with knowledge that the product will be as promised (high-quality product) through advertisement and therefore were given the products, it was not high quality but instead low-quality products, in regards to unconscionable conduct, how would they handle the situation? Could you please include how section 21 and section 22 of Australian Consumer Law may affect the issue.
