Indian Railways — response from ahamadnagar railway police

Sir,

My name is mayur bondre. On 2/09/2017 i was travelling from nagpur to
Pune in hatia express (22846), coach s9, seat no, 71.

In between kopargaon and ahamadnagar someone snatches my mobile phone
And jumped from the running train. I had too tried to catch him but
Train is not so slow that i can jump. So pull the chain and ran
Towards the the thief but he escapes.
After pulling chain, no one came there to ask nor the police come to
Check who pulls the chain.
So i request you to please the help me to find my mobile. I had
Purchased the mobile only three days earlier on 29\08\2017.

I had complaint about it on email id of ahamadnagar railway police, but i didnt received any response from them. I am continuously mailing them. But not even single reply was received.
Please take some action
Thank you
