P&SC Grievance Reporting Platform

TNB uses Whispli, a secure and confidential third-party platform to protect your identity and support transparent reporting.

You have the option to remain anonymous, and no personal identifiers—such as username, email address, or IP address—are shared with TNB. The platform incorporates strong data security measures, enabling you to safely submit messages and upload supporting documents.

You can monitor the progress of your report at any time by selecting “Follow Up” within the platform or by downloading the mobile app to receive real-time notifications.

 

What happens to your report after submission?

All submissions are handled in accordance with TNB’s grievance procedures — registered, assessed, investigated, and resolved. A neutral P&SC Grievance Committee ensures fairness and impartiality throughout the process, while the P&SC Grievance Admin provides progress updates via the P&SC Grievance  platform. Please monitor the platform regularly to stay informed and support timely follow-up.
