How to claim insurance for the car that was stolen 2 years ago

My car was stolen almost 2 years ago. I finished all the formalities with the police (they filed an FIR a week after I gave a written complaint), and then I submitted all necessary documents to my insurance agent. After a month or so, he said that he had misplaced the documents and that he'll prepare another set of those. Now he says that he submitted the documents in the regional office and they might not have taken any action as the FIR was filed a week after the incident. So what should my next step be? PS : He insists me on complaining to regional branch officer that I had been to the regional office along with the agent when he submitted the documents. Should I do as he says or stick to truth? (I'm confused as I haven't received any acknowledgment after submitting documents to the agent)
