A brief introduction about me : I am a student aspirirng for ALL INDIA JOINT ENTRANCE (JEE MAINS). I belong from a village from the state of wb. I live in a community where more than 300 KARMAKAR people live. We all had SC certificates because we belong from the LOHAR caste. Now in 2021 the SDO of our division collected all the caste certificates from us forcefully. He ordered us to show appropriate proofs showing that we belong from the LOHAR community. Now when we showed documents from the 1990s , he declined and said that the proofs must be from the 1950s or more older. And as expected we failed to show such proofs. He than told us that he woold cancel our certificates. But after almost 1 year all the certificates are still not cancelled (they are showing active status in online portal) . What should I do to get back the certificates ?
