India Post — Misplaced my shipment

Address: 173234

Website: indiapost.gov.in

I had shipped my shipment using speed post with tracking no. EE[protected]IN.
It has not been delivered till date and now they are not even showing the details. Please look into the matter as the shipment was of high value. Indian postal service has been negligent and irresponsible on their part. Ihad even filed a complaint against this tracking ID wich was rejected by them. it is a strong case of financial and mental exploitation of a consumer. I demand a strict action against the culprit.
