I placed a order for a product "sony alpha a6000y 24.3mp digital slr camera (Black) with 16-50 & 55-210mm lens (Ilce-6000y)" on 8 june 2017. I paid fully by credit card. On 11 june 2017 the tracing detail shows the item was delivered and receipt was signed by me (Debashis sardar) whereas i did received the item at all, hence there is no question to sing in receipt, but they claimed the receipt was signed by debashis sardar. I fear courier service grab the item. It is cheating case was happened by amaxon.
