I ordered a nike shoe through Rediff shopping cash on delivery and it delivered to me on time but I don't like product quality so I want to return it but company said call to vender and I called he also agree to take return and refund my money. But when I call Rediff shopping again then company said wait for mail and once you receive mail courier this product on address which mentioned in mail.but it didn't get mail it's been 2 week. And today I called once again Rediff shopping but as usual he said wait and company ignoring me and not taking my shoe return. When I am buying shoe that time company said if you don't like you can return we are refund your money. But after I brought shoe company ignoring me. So please I request you to take immediate action against company. I attach my invoice bill below.
