Flipkart — Order not being delivered even after reaching the nearest hub

So I ordered Apple iPhone14 on Oct7 and it had to be delivered the same day. It is Oct14 now and it has still not been delivered. I have called and raised complaints multiple times to the flipkart customer care and it has still not been resolved.
It shows out for delivery and then again unsuccessful delivery.Even if i call the delivery agent he either doesnt pick up or rejects the call. Sometimes its not even out for delivery and shows unsuccessful delivery. I want it to be delivered by tomorrow as I need for work purpose...Please get it delivered by tomorrow at the latest.
