Flipkart — Grocery Items not delivered from last 6 days

I ordered groceries on Flipkart with the expectation that they would arrive on December 5th, but they have not arrived as of December 10th.
Not cancelling the order and not refunding the amount, already committed to deliver twice this week but not delivered on time. Day by day, Flipkart promises that tomorrow will be the same. However, the products have yet to be delivered
