India Post — Delay in delivering and respond to complaint as delivered

An article booked from Aluva HO on 11/12/2021 to kharagpur technology SO consignment number. EL[protected]IN. Recieved at Kolkata AP TMO on 13/12/2021 as per tracking.
From then no updates, a complaint registered with india post no. [protected], shows the article delivered and on contacting customer care service, it is said that it got delivered to brahmapur SO. Why such mistakes of delivery and the item is of immediate concern. When will I get my article. And due to the delay I am suffering monetary loss, will it be addressed by the india post?
