My order was not delivered to me yet and when i called dtdc employee yesterday delivery he told me that he delivered the product to some else, today he is saying that the product went return again he is saying that there is sign on the sheet saying that the product is delivered, but i didn't received it yet. Can i know what the dirty things are happening with you people, is this how you react with customers.
