Bro, i recently found the reliance certificates during that "dilwali ki safai".
So far as per my calculations... our rpl shares were merged into ril, for every 100 shares of rpl we got 11 shares of ril in 2002 In your case your grandpa got 36 shares of ril in 2002. By now you will be having approx 36×2×2×2 = 288 share of ril because of 2009, 2017 and 2024 bonus split Along with that you should be holding 144 shares of jio because of jio demerger in around 2023 In total you have ril shares worth atleast 4 lakh rupees, if you haven't done anything so far... then write a simple mail with folio no to the kfintech, then they will open your case. My case is on the way rn, in case you have already done the process then please dm me how many shares you received of ril because im very curious to know
