Flipkart — Seller closed complaint without providing refund

Address:

Flipkart Coimbatore

My order ID OD[protected]. Out of 15 items, I received only 11 items. This is happening for the past 5 months, last time I was assured from Flipkart team that this won't happen again, but again got missing items. This is repeating again and again and when I complain in customer support the seller is closing the complaint without any resolution. Why there is no strict policy in Flipkart against sellers and it is not customer friendly. I want my refund or items and make sure that this we I'll not repeat in future grocery orders
