India Post — missing items sent from abroad

Address:

Ernakulam, Kerala, 682307

Recently i purchased a custom made silver ring from ukraine. The ring cost me nearly 100 dollars. The order was placed by me on july and i received the package on 19th august 2019. I was simply heart broken to see my ring missing. I was furious and wrote to the manufacturer and he assured me that it was stolen once it entered our country.
When i dug deeper i found similar cases in the internet. I don't know why these people who are responsible for safely delivering the package resorting to such dishonourable acts.
Shame indian post... And that shame also falls on the country's name.
Is there any way to help me, my good sir?
