I have ordered Camera Nikon D7000 +Tripod +Camera Lense from Snapdeal.com.We have placed an order(Order no:2642318067) on 17th august,2014 and they assured they would deliver the product within 7-8 Days.First they have delivered only the tripod .So we raised a concern for partial Delivery of the product .Its been more than a week and still we dint erceive the product.I have been mailing them several times and had calls with them but they only say that the monet is on trust pay and would delibver the product or refund the money. Please take an action so that we receive the camera with no defects or refund the money back.
