Delhivery — Product was not received by the customer

I have ordered an AD necklace set on 14 june. It was shown as delivered to the sender on 22 june, but I have not received that one yet. Even no calls or contacts has been made to me during the delivery. But when the delivery proof has been sent to me, even the sign on that was not mine.
I think someone else received that or there was some problem during delivery.
So, kindly it's a request from the customer to look after the matter seriously, if possible go in detail of the tracking or the recipient of the parcel.
