Customer Complaint Management is the structured process of handling, tracking, and resolving customer grievances in a systematic and timely manner. CRM systems enable businesses to log complaints, categorize issues, assign cases to appropriate teams, and monitor resolution progress. Features like automated case escalation, AI-driven sentiment analysis, and self-service portals improve complaint handling efficiency. Effective complaint management enhances customer satisfaction, prevents churn, and strengthens brand loyalty. Industries such as telecommunications, banking, and retail heavily rely on CRM-driven complaint management to ensure compliance with service level agreements (SLAs) and maintain customer trust.
