Vistara — Travel Insurance not able to add against my PNR

Address:

Neelancheri Kandiyil house

Im the Vistara club member[protected] and received one welcome voucher of premium economy flight ticket and redeemed that voucher against KZ7SLJ and the traveler name is Muhammed Hijas.

Normally when we travelling any transport (bus, train, flight) there is an insurance default added or we can add by ourself against the ticket.

Here I'm not able to add any travel insurance against my PNR KZ7SLJ.

So i want the compensation for the above issue.

Kindly sortout the problem.

Regards,
Ajmal M
