India Post — Delay of my parcel

I had booked a parcel on 17/03/21 and today it is 14/04/21. The status of my consignment shows received at Kolkata TMO on 31st of March. India post customer service is pathetic. No one can answer queries. Poor service will never use it and ask people not to avail the poor service. I have raised a complaint too but there is just no response My consignment number- EW[protected]IN. Kindly revert
