Level 1: Customer Support (Initial Complaint)
How to complain: Do not search for random toll-free numbers online Petronet LNG does not operate a retail household consumer helpline. For official corporate, vendor, stakeholder, or investor grievances, call the Corporate Headquarters directly at +91-11-71233525. For written complaints and shareholder grievances, email the Company Secretary and compliance team directly at investors@petronetlng.in. For online tracking, you can use the official contact portal at petronetlng.in/contact-us. Ensure you receive a formal written acknowledgment of your grievance.
Availability: Standard business hours for the corporate office are Monday to Friday, 9:30 AM to 6:00 PM IST.

Level 2: Formal Corporate Escalation (Notice of Dispute)
Who to contact: If the initial desk (Level 1) fails to resolve your issue within the stipulated time, you must escalate the matter formally. You can send a formal written complaint via registered post to the Company Secretary / Compliance Officer at Petronet LNG’s Registered Corporate Headquarters: Petronet LNG Limited, 4th Floor, Tower I, World Trade Centre, Nauroji Nagar, New Delhi - 110029, India. For share-related physical escalations (if your demat query isn’t solved), you can also copy their Registrar & Share Transfer Agent (Bigshare Services Pvt. Ltd.).
Timeline: You should legally provide the corporate office a 30-day window to investigate and respond to a formal written grievance before escalating to external authorities.
Level 3: Regulatory Authority (Government Ombudsman)
Authority: Petroleum and Natural Gas Regulatory Board (PNGRB), Ministry of Petroleum and Natural Gas (MoPNG), or SEBI.
Portal/Contact: If Petronet LNG fails to provide a satisfactory resolution within 30 days, your escalation path depends on the specific grievance:
- For Corporate Compliance & Shareholder Disputes: File a grievance online via the SEBI SCORES portal at
scores.sebi.gov.in. - For Natural Gas / Pipeline Regulatory Disputes: File a grievance directly with the sector regulator, PNGRB. You can email them at contact@pngrb.gov.in or call their board line at 011-24060151. You can also write to their headquarters at E-400, 4th Floor, Tower-E, World Trade Center, Nauroji Nagar, New Delhi - 110029.
- For Public Sector Administrative Grievances: File your complaint online via the Centralized Public Grievance Redress and Monitoring System (CPGRAMS) portal at
pgportal.gov.in.
Level 4: Legal Action (Final Step)
Pre-Litigation: Ensure you have documented all previous correspondence, contract papers, investor folios, and email trails. Send a formal Legal Notice via an advocate to Petronet LNG’s Nauroji Nagar registered office in New Delhi, providing a standard 30-day window for settlement.
Court/Arbitration: If the legal notice is ignored and the resolution is still unsatisfactory, the final step depends on the nature of your dispute. Vendor and commercial contract disputes must be resolved through arbitration clauses or the High Court/Commercial Court. Consumer commissions (e-jagriti.gov.in) are generally only applicable if you strictly meet the definition of a “consumer” under the Act, which is rare for B2B LNG disputes.
