Industry: Public Transport (State Road Transport Corporation)
Jurisdiction: Tamil Nadu, India
Primary Regulator: Transport Department, Government of Tamil Nadu
Important Safety Warning: Beware of the massive “Refund SMS Scam.” Scammers frequently send SMS or WhatsApp messages stating: “Dear Passenger, your TNSTC/SETC ticket refund has failed. Please click this link or call our officer immediately to process your money.” This is a scam. Authentic TNSTC staff will never send alerts from a personal 10-digit mobile number, nor will they ask you to download screen-sharing apps or pay via personal UPI links.
Level 1: Customer Support (Initial Complaint)
How to complain: Register your complaint (ticket refunds, bus delays, staff behavior) directly via the TNSTC Official App, the web portal, or by calling the Arasubus centralized customer care toll-free helpline at 1800-599-1500. For specific online reservation and e-ticketing support, you must call their dedicated cell at 9513948001 or 080-66006572. You can also send photos/videos of your grievance to their official WhatsApp Complaints cell at +91-9445014448 or email the commercial desk at commercial@tnstc.org.
Availability: The central helplines, WhatsApp cell, and online portals operate 24x7. Official Bus Station Enquiry desks operate during standard daytime hours.
Timeline: Standard service requests and refund initiations must be acknowledged immediately. TNSTC aims to process online refunds within 14 days and resolve standard operational grievances within 7 to 15 working days.

Level 2: Internal Escalation (Branch Manager / Managing Director)
Who to contact: If Level 1 support fails, your refund is stalled, or your ticket is closed without a fix, you must formally escalate the issue locally. Submit a written complaint or call the specific Branch Manager (BM) or Deputy Manager (DM) of your origin/destination depot. If the local depot fails to resolve it, escalate directly to the Managing Director at the Corporate Head Office (Thiruvalluvar House, Pallavan Salai, Chennai – 600002).
Timeline: Under standard administrative guidelines, the Depot or Corporate officers must address and resolve escalated ticketing and service disputes within 15 to 30 days.

Level 3: State CM Helpline (Mudhalvarin Mugavari)
Authority: If the TNSTC corporate officers reject your claim or fail to resolve the issue, you must escalate to the state government via the Chief Minister’s Public Grievance Redressal System, also known as Mudhalvarin Mugavari.
Portal/Contact: You must submit your grievance to the state government via the cmhelpline.tnega.org portal or by calling the central CM’s grievance toll-free line at 1100.
Timeline: Grievances escalated to the Mudhalvarin Mugavari portal are tracked with strict Service Level Agreements (SLAs), legally mandating a formal investigation and a targeted resolution response within 15 to 30 days.

Level 4: Consumer Court (Legal Action)
Pre-Litigation: Do not use central CPGRAMS for state utilities. Public transport service deficiencies do not require a specialized Ombudsman. If the CM Cell portal fails, the National Consumer Helpline (NCH) via 1915 is your final pre-litigation step.
Court/Arbitration: If you are aggrieved by unrefunded tickets, severe delays causing financial loss, or gross negligence, you must file a formal complaint with the District Consumer Disputes Redressal Commission under the Consumer Protection Act, 2019, utilizing the e-Daakhil portal.
Timeline: You must file the case within two years from the date the cause of action (the service failure) arose.
