Ybm Travels — lost my wallet

I traveled from chennai to trichy on sleeper bus. When i was waiting for bus in my stop driver went without stopping in my stop. I called him immediately and he asked us to come to next stop the time already 11.30. Then i went to next stop in auto and boarded bus. When i got down at trichy i checked my wallet was missing (I m sure i had it after i boarded bus). So immediately i called driver and asked him to wait at next stop and i reached there in auto but couldn't find my wallet. One thing i noticed was before i get down i did not fold my bedsheet but when i went to search my wallet it was neatly folded. Driver said me that he will search completely after reaching madurai he was very polite and genuine. I called him again after two hours that is after they reach madurai helper boy attended the call and he was very harsh and asked me to give a police complaint. I had all my id proofs in my wallet atleast i need that. Help me in getting that.
