Delivery agents scamming customers

I used to send my family products ordered from amazon since years. From the past one year or so they have been getting opened boxes or boxes are sealed but products are missing etc. Amazon has been kind enough and has helped. I asked my friends living in the same city, a small remote tier iii city, they said there is only one amazon warehouse there.

This warehouse has hired supervisors and they hire delivery agents under them. For our city there are four of these supervisors. So, what they do is they hire temporary delivery agents, pay them very less and tell them that they can do whatever they want with the boxes but they need a cut. The exact financial details are not with us but this was told by many delivery agents who left the company. Most of them work their on fake kyc records and many of them are anti social elements. A few of the delivery agents were caught in front of a park opening customer boxes sometime back and the video went viral too but they are still coming for delivery sometimes.

Since mostly everyone in my society was getting missing products, sometimes even whole product was replaced so we all have complained to amazon directly too. They don't care if we give them this info, they are like we are solving your product related query that's it. If you have any other issues then contact the law enforcement. But as our parents live there and we have nothing to do with the company so there is no point in involving the law enforcement from our side.

We have all shifted to alternatives like flipkart etc. but still mostly prices are less on amazon. Came across this sub so thought of asking, is there any way to report this to them somewhere where they will definitely take action? All of us tweeted, mailed to grievance. Sometimes they called back but literally zero action was taken.
