Credit Information Bureau India [CIBIL] — 53 point steep fall in credit score

Address:

mumbai

Steep fall of 53 points 2 years back, and still not specific reason provided yet And every time i raise the complaint anywhere another 2-3 point is reduced which returns to just marginally up of 800+ (801 or 802) as per current performance. Pretty sure about another reduction of points after this complaint presently its 803, will definitely revert on change.
Since last 2 years following up with cibil by many options mail fone, escalation, till today not a sigle person have a clue of 53 points fall in my credit score and always they share generic reply like a bot.
The problem is this company doesn't falls in RTI and they had returned my rti by saying we aren't liable to respond any RTI as they aren't covered under RTI Scope
