This complaints is regarding order no[protected].
I ordered a shoes from Flipkart and payment of Rupees 389 is paid through my credit card.
The estimate date of delivery was 29 August 2019.
No any call on 29 aug is received to me neither on my registered number nor on my bill address details. Order was not received to me on 29 but online tracking was showing that the order is delivered. Next day i call to ecom service number they told me that your order is placed, ask to your neighbour or your main gate( I lived in a Hospital Complex). Then i checked in my main gate and my order was placed in a table that was not secured.
My order was prepaid. courier service not given my order in safe hand. No sign from receiving person was taken, no proof of identity was taken.

Now after complaints on 30 aug they ask to bring me a copy of your Id proof.
