Even if you default on a loan, lenders still have the legal right to collect their money, but they must follow proper procedures. According to industry expert Anshi Shrivastava, borrowers who are being harassed should start by collecting evidence. You should first file a complaint through the lender's official grievance system. If the issue remains, you can escalate it via the RBI's complaint portal. In cases involving physical threats or violence, you should contact the police immediately.
