CIBIL — credit score incorrectly showing no history

Website:

www.CIBIL.com

I have been following up with cibil for a correction of my credit score that shows 'no history' even though i have 3 active accounts and 8 total with 13 years of credit history, and have confirmed with my banks reporting them on time. Despite relentless followup with cibil last 3 months, their standard response is - working, will get back shortly. Meanwhile, validated my score with experian (From paisabazaar) and it does show all correctly. Clearly, this is highly reckless job by cibil not bothering how much pain it causes when one seeks credit from banks/fis. Sounds like they can be absolved without any accountability. The website has nicely documented escalation process that i have used but to no avail, get always a standard response.

Any suggestion/help where to raise these issues? Rbi contact or somewhere else?
