Selling inferior quality products

I bought a Tefcold wine cooler and when it was delivered with a number of dents and a skew and loose door handle. I complained about it and was told that the supplier don't have stock to replace it (even though Megastar still has it for sale on their website) and was then offered a discount. I have in the meantime done more research and discovered that this company is not a listed distributor of Tefcold and that this particular model that I received with "Made in South Africa" stickers on it, is only manufactured in China and that other suppliers import this from Denmark (not manufacturing it locally). You clearly don't get the product you think you are buying from this company. I have also not received any further responses to may mail requests/queries.
