Hi, My wife purchased some replacement fire bricks for our AGA wood stove online from a company in Melbourne. The first consignment never arrived and after complaining to the courier they ordered a replacement set at their expense. Today, the replacement bricks were delivered and one of those bricks has been broken. These are not standard bricks but are specially molded and created to withstand high temperatures and cost around $500 for a set. So the question is, to whom should we direct our complaint and is there anything we can do if they refuse to address the issue under Australian Consumer Law?
