India Post — Failed to give service in time

It is a Registered letter. I posted an application to district collector office last dated 04/05/2017. I posted it on 27/04/2017 but it didn't delivered to the destination address. It was sent to bilaspur 0n 28/04/2017 but then it didn't proceed further. The consignment number of registered letter is RC[protected]IN. It is a job opportunity for me but application will not be received.
