India Post — The item I ordered has been dispatched from Ma Ranchi RMS TMO five days ago but no updates after that

I had ordered books from Mumbai, which were booked on 04 Aug 2023 at Kalbadevi H.O(400002) and had to be delivered at Shikherjee H.O(825329). The consignment has last update of 11 Aug in which it's showing that the item has been dispatched from Ma Ranchi RMS TMO at about 18:57:28 but no updates after that. Today is 16th and it has been so many days I am waiting for any further updates. I had contacted my local post office regarding the item but they haven't received it yet. And the concerned Ranchi post office (RMS TMO) is not picking up calls even. Means at the end of the day, I am stuck getting help from neither of the sides.
