Reliance Jio Infocomm — Request to retrieve my disconnected sim

I have lost my sim unfortunately before 3 months at my old home when get shifted to new home. But luckily I found it today with no network. When approached Jio customer care they said the sim got disconnected around end of August and it is not possible to retrieve the sim. When I asked the possibility of re activation since only 5-6 days from disconnection, they said no... I'm requesting you to kindly take action to retrieve my lost sim.
Kindly do the needful request.
