India Post — Missing contents in Parcel

I had recently received a parcel through the Indian Postal service, and to my surprise, it was found to be opened and several contents were missing. The parcel appeared to be sealed and at a passing glance, seemed to be in proper condition. However, on close observation, it was evident that the parcel packet has been tampered with. The brown tape on the side, which had been opened to steal the contents, was cleverly replaced with transparent cello tape. Several contents including a few dresses and a school bag were missing. There was another grocery bag inside the parcel that was torn probably during the theft.
My mother-in-law had a similar experience 30 years back when her wedding sari was replaced with an old torn sari when she had sent it through the Indian postal service. The internet is filled with similar complaints of thefts against the postal department for many years, but it seems no action has been taken, or else it would never have continued to date. It is a huge shame and a black mark on the Indian postal department and its employees. It is not surprising that people have started to lose trust in the postal department and instead have faith in private courier services. People struggle hard to get a government job, but such greedy and undeserving employees who resort to such unlawful practices are a disgrace to the system and the society. I kindly request the authorities to nab the guilty, bring them to light, and save the postal department from extinction.
