[Resolved]  Safexpress — product lost

I had sent two boxes from jamshedpur to ghaziabad on 09th may 2018.
The waybill number being : 58937687.
The boxes had my valuables in it.
However when i called safe express they say that they have lost one of the boxes.
One box was delivered to me on the 26th of may and the other is still not tracable.
They are not bothered about looking for the box rather they are just asking me to take a claim of rs.5000.
The box has things which are of higher value than of rs.5000.
There is no response from their end and they are not looking into the matter seriously.
I want my box at any cost.
It is extremely important
And if they admit that they can't get it done then they should give me the value of the goods in the box.
