Thanks for your input! yes i have all proof earlier cibil report with control number and this cibil record with control number, Call recording of sahafinlease executives, i wrote email already to shahfinlease , asusal they not replied , i just googled shahfinlease is notorious for this cibil slaughter and paid compensation to customersYou are definitely mistaken for some other person (maybe with similar name or similar PAN)...
Otherwise it's impossible that you had loan default for 25 years and CIBIL score is dropped now...
Write to shahafinlease first... Wait for reply... If no positive answer then re-write to them...
Then write in RBI ombudsman attaching mails and their reply plus latest CIBIL reports... Keep in mind to show your last month cibil report too which doesn't show any such loans...
I had earlier given you the performa for the mail
