Overnite Express — urgent courier not delivered

Website:

www.overnitenet.com

My shipment no [protected] was sent on 5th July 2018 to Rohtak from Gurgaon.
Its status shows delivered on their website but it hasnt been delivered yet. It has been a week.
No call was made before delivering the courier.
Nobody even receives a call on the customer support number. Tried emailing them but got no response there as well.
Highly fraudulent behaviour on their part.
