I had told you in my Reply on "July 23, 2014" that if you pay anything less than what is owed to the bank, the Status Column will indicate something like Settled, Written-Off, etc
1. If you want to re-open the case, you can do so. For example if you owed Rs 65,000 to HDFC Bank and assume you have settled in 2010 for Rs 40,000. Now if you want CLEAN CIBIL CREDIT HISTORY, bank is willing to do so. You will have to pay just Rs 25,000 + Interest on the same for the last 5 Years. Once that is paid, they will update the CIBIL Status i.e it will be left blank indicating Account Closed with Full Payment.
2. How do you re-establish the History ?
Get a smaller Loan - Bike or Consumer Durable and Make Timely Payments.
Get another credit card and spend few hundreds every month and pay off in full.
3. CIBIL Score will increase by higher proportion with payment track record on Secured Loans (Home, Car, etc..)
