Grievance redressal
If you have a complaint about a loan you applied for through Finsa, raise it from your application page first: it goes straight to the lender through ONDC, and the lender must respond. If you are not satisfied, contact Finsa's grievance officer.

If your complaint is not resolved within 30 days, you can approach the Reserve Bank of India's Integrated Ombudsman at cms.rbi.org.in about the lender.
