Flipkart — Intentional harassment with the objective of monetary benefit

It's the worst app to order groceries, I have ordered 5 times now, and out of these just 1 of them was a smooth delivery, the rest were never delivered on the day promises and the support assistant would raise a case with a 72 hour TAT and that too is extended so basically I am without the necessary groceries and have to get it again from the market and, flipkart would hold on to your funds for 5-7 days without a resolution, I feel this is a scam by flipkart to feed on the interest accrued on the amount withheld for millions of such customers
