Vistara Airlines — website

I have booked airticket through your website to travel from srinagar to kochi on 06 aug 17 for my wife anju p. Pnr is kfzoc3. During booking your website demands more than one letter for the last name. So that i was compled to add peethu instead of p as last name for my wife. Now it bocome security issue as a airport like srinagar. I have contacted your customer care ms poushali to solve the issue afterthat i have paid 1000/- to change the name. Its purely wastage of time and money for me. Forwarding my grievances...
