This Amazon delivery guy Vinuth M mobile number [PHONE8147226432] in Bangalore came to our flat with other amazon prepaid orders saying that one item is not paid. I paid him 699 on the qr shared. later when i checked my order history this item was not there and i called amazon. Amazon asked me to open and take pics to find it had garbage in it. And they took my fraud case for investigation.
