Flipkart — Refund not happening by flipkart for missing product in grocery

Address:

bangalore

Hi,
I ordered online flipkart grocery via Order number OD[protected]. Related deliver person just put items on my door in my absence. and also did not informed me. He did not put 11 items out 35 items. Now even after complaining to flipkart customer care they are simply rejecting refund or delivery of items by saying seller confirmed delivery.
They have 3 items still pending to refund of higher values which they are rejecting for refunding:

Delivery time:[protected]

1.
LOTUS HERBALS Safe Sun Sunblock SPF 30 PA++, Sunscreen -----216 Rs
2.
Flipkart Grocery Classic Desi Ghee 1 L Tetrapack -- ₹540
3.
Farmley Premium W320 Raw Kaju Cashews ------- ₹342

It is really painful to follow customer care continuously an later refund simply get rejected from backend.

Please help to resolve issue with flipKart.

Regards
