Shopsy — My prepaid order is delivered but I haven't received any parcel.

Website: Shopsy/ Flipkart

My prepaid order got delivered but I haven't received any parcel from flipkart.
But In my order section it is showing that your order has been delivered.
I don't know how is it possible? I haven't shared ky OTP with anyone else and without providing my OTP how the hell my order got delivered!
