Flipkart — Failed to deliver my package.

Website:

Flipkart.com

I ordered a headphones worth ₹1299 + security charge ₹10 totally ₹1309. On 15/01/2023 Order ID - OD[protected]. It promises my order will deliver on Thursday 19/01/2023.
But my order doesn't reached still on 21/01/2023. It shows the delivery agent number and when i call him he toll that "we don't have delivery agent on our location so we can't deliver your product ".
If they don't have deliver agents why do they says we do deliver all over india?..
