Delhivery — Courier boy lost my courier

Hello,
Awb no[protected]
Courier boy has lost this item. It was not delivered to me. I registered a complaint also at that. But he said he will pay me for this item . I should take back the complaint against them. But from last one and half month he dint even done payment to me and when i call him, he talk rudely and said do whatever u want.
I need action against him.
