Hi! Thanks for the question! Here you will have to give time to the situation, as you stated that you completed your M. Com in 2012, it has been a long time since your HSC and SSC(Usually it is difficult if it is past 5 years since your results were declared). Procedurally, you will have to get an application forwarded by your principal or the concerned authority from the school to the board that your school falls under. The board after due scrutiny and checking according to the school records and permissions will send the corrected certificate in 7-10 days.
If this does not work then you will have to file a Declaration Suit in the Civil Court where you stay and have an order passes to resolve the problem.
I hope you have some clarity about the procedure! Good Luck!
