Ekart Logistics — Sending orders which I never ordered on COD

Order No. SHOC[protected]. I or anyone from my family never ordered this. It came to my address for COD of 499. I spoke to flipkart and they said I did not place nay order. Who ordered it and when. How can it have my exact address and phone no. They are scamming people by forcefully sending some orders and asking money in the name of COD.
