India Post — consignment status not shown as delivered

I had sent one envelope on 24.09.2018 from panaji goa to ignou study centre kochi kerala. But the status of the consignment is still shown as dispatched. It should reach the ignou office by 11th october. The id is em[protected]in. Please help me with this. It's my re-evaluation exam form i had sent. The ignou office people are not telling anything about whether it is been received by them or not and are telling to confirm with speed post india.

I also had attached a dd to the form.. Its really urgent for me to know about the delivery details else i need to answer my exam again.. Do the needful as early as possible
