Delhivery — No attempts to delhivery

My order is being shipped via Delhivery and the shipment has been out for delivery on 31th but it never reached me got the reason that I did not pick up the calls which were actually never made since I never received any calls the shipment was out for delivery today also but no-one came and no calls no msgs
every day those deliver agents are out for delivery but no-one shows up & next day in the morning I get a message that no one picked up the call no delivery agent's contact details provided
