TNSTC Customer Care & Helpline Numbers
About TNSTC support
TNSTC lists at 149 as its customer-care line. Callers typically use it for account trouble, order or booking issues, refunds and service complaints. For anything that is not urgent, writing to commercial@tnstc.org usually gets a written reply you can refer back to. If the service itself seems broken, glance at its live status page first — the problem may be an outage rather than something on your account.
