India Post — misdelivery of the speed post article despite showing delivered

Address:

Ludhiana, Punjab, 141013

I am jasvinder kaur from ludhiana and had placed speed post order containing important business goods on 17 september 2019. It was dispatched from basant avene post office and was to reach panipat.
I had checked the tracking details which shows that item is delivered on 19 september 2019 but the addressee hasn't received it tell now. Maybe the consignment is misplaced or not correctly delivered and the indian post clerks aldo don't help me. Please resolve the issue as earlier as possible.
