India Post — Speed post courier not delivered n

I have couriered 2 parcels on 30 june 2020 through speed post. It's already been 10 days but it's not delivered yet. Also when i try to track my consignment it doesn't show any update after 1july 2020. Those two courier contains important documents that need to be delivered to my college as soon as possible but it hasn't delivered and i am facing problem because of that. Consignment number of those courier are: ef[protected]in and ef[protected]in.
These are to be delivered to rohtak from muzaffarpur.
