[Resolved]  India Post — Addressee not found

I had placed an order for some items on an online website a few weeks back. The seller dispatched the parcel on the 14th of July, 2021 via India Post. Today is the 20th of July. The seller had given me the tracking ID which is CH[protected]IN and today in the morning I was tracking the order on the Track Consignment page of India Post website. Delivery was attempted but the status showed "Not delivered. Addressee cannot be located." But this is absurd because all my online orders and mails come to the address that I had provided to the seller. I don't know why it happened but I demand my parcel to be delivered immediately.
