RETURN OF SUBSTANDARD PRODUCT

I bought a product from Game and was not happy with it. I attempted to return the item the next day but was told that i can only return the item if there was something wrong with it. I explained to the lady at Game Gateway KZN that the product was substandard and did not work as expected but she refused to credit me for it. I would have opted to take the same product with but with a different manufacturer however Game did not keep any other manufacturers product. I am a regular customer and was extremely disappointed.
