India Post — Article not dispatching yet from kol ap tmo

My mail parcel reached at kol ap tmo on 10th Nov, 2021. On tracking site it is only showing the mail parcel at kol ap tmo from last 1 month approx. I am not able to track my parcel further. Also not getting any updates about the same as I have already contacted the customer care executive more than 10 times. It's an very important mail and needs to reach the destination as earlier as much because it's already too late. Kindly resolve my problem as soon as possible and update me about the same at the earliest.
