Investor grievance redressal via centralized complaints system mandates brokers to resolve complaints and exchanges to enforce penalties. Redressal of investor grievances is centralized via the SEBI Complaints Redress System (SCORES), which provides a central database, online complaint routing, ATR uploads and investor tracking. Complaints against brokers and sub brokers are communicated electronically to exchanges, which must pursue the matter with brokers. Brokers and sub brokers must redress grievances and inform investors/exchanges within one month, failing which brokers face penal action; exchanges must follow up, levy penalties for noncompliance, update SCORES with status and documents, and align website disclosures with SCORES.
