India Post — ems from saudi arabia not yet delivered and not traceable

I sent documents through ems from saudi arabia to pune on 05/09/2018. Saudi post tracking system showed the tracking of the docs.
The document has reached up to nsh mumbai on 09/09/2018 as per saudi post tracking. After that saudi post, when contacted told me that in destination country local carrier has to provide tracking i. E india post. But after that further tracking of the document is not available and it is yet not delivered to the destination. Please do needful...
