Rapido — Stolen my package/not even refunding the money back

Rapido pickup person came at my place and picked the item that was supposed to be delivered at another address. But after sometime he just cancelled the booking and never called back to return the package or never tried to deliver it also.
Now, as I complaint to rapido about this after 4-5 days they are coming with the resolution of refunding me a sum that is nowhere close to actual cost of the item. And they neither contacted that pick up person also, I requested them to just return my package back if they are not able to refund my money. Actual cost of package was around rs 10000 and they are refunding only rs 500.
I need my package back please help me. Or atleast refund of the package.
