Flipkart — Delivery of order tracking # FMPP[protected]

Above mentioned order was supposed to be delivered on 9th of April 2023 before 2 PM. However, I am still waiting for the delivery almost 2.5 days beyond committed delivery ETA. The product reached nearest eKart hub well in time. Ironically the hub is approximately 2 kms from the delivery address.
Each day the status is marked as out for delivery in the morning and then the same is falsely updated stating no response from the customer. The truth of the matter is that there has not been even a single call made from eKart.
In fact I have tried calling the shared number of the delivery person several times only to hear them disconnect the calls without receiving them.

Only time they picked up the call was on the morning of 9th April 2023 giving me a tentative time of delivery as 6-7 pm while at the same time expressing their disinterest in delivering an exchange order (this order is for a cell phone with exchange option of an old one). But no one turned that day and responded to any further calls from my end.
