Yes they do sound like knock offs but I do not think it is the company's responsibility. Where did you buy them? If you bought them at the brand's store or a department store then it is the company's fault. However, if you bought them online or from a private seller then there is not much you can do. If it is on ebay then you can give the seller a bad review or complain to ebay about false advertisement and try to get your money back. Good luck!
