Correction of cibil

Dear Sir, I am Ardhendu Kumar Das i took a deutsche bank Credit card in the year 2008 and bought a mobile phone worth Rs 8000/- at that time and converted the same into 9 months EMI but unfortunately one of my EMI bounced due to which they called me for the payment which at last i made in the same year by calling there collection executive at my work place and settled the accounts. In the year 2012 when i applied for a car loan i found that my CIBIL score was low due to certain credit card with and overdue amount of Rs 139965/- when i saw the report i saw the card pertains to indusind bank when i inquired i found that the credit card division of Deutsche bank has been acquired by Indusind Bank in the year 2009. So to rectify my CIBIL i sent a mail to the customer care of Indusind bank and explained them the full case but they told me if you want to rectify your CIBIL you need to pay the entire amount. So i decided to drop the plan for time being but there collection department continuously called me to clear the dues they sent there executive to my home address and took numbers of my parents Now they have started to misbehave with me and my parents and started to threaten to assault me by local gundas. So i decided to pay the settlement amount but on certain suggestions offered by other banks i asked them to sent me a consolidated statement which shows the principal amount due, break up of interest and late fees so i asked them to send me the same there officials told me that it is not possible for them to give such statement so ask it from customer care so i sent a email to there customer care but they didn't replied till date and now the scenario is that there collection department has again started to make threatening calls. So please suggest what can be done in this case.
