Delhivery — Loss of washing machine

Washing machine was sent from my native village (Baramati) to my current location(Kopar khairane, Navi Mumbai) via Delhivery courier service. MAchine is not received to me but delivery boy is claiming that machine is delivered to you. I asked him to show his call details, he is refusing to show. I have document proof of LRN number and drop off receipt photograph.
