Delhivery — Product not getting delivered and they are rescheduling

My Tracking ID is[protected]. My luggage had been picked from Lucknow and already reaches Bangalore on 13th however delhivery team is nether responding to my calls nor confirming of the delivery.
Once I am trying to track, it says rescheduled and just a few minutes before someone called to inform that one of the parcel has been misplaced by them thus they are rescheduling it.
Kindly address this on immediate basis as I am really not sure if product is in safe hands or not
