Dt 19/09/2016 at 14:24 IST for PNR no YGL42U, I need Travel certificate from Airline and made a online request and made payments of Rs. 200.00 through my credit card of ICICI bank, but till time nothing is happens nor any TC given to me for said PNR no YGL42U.
After that since that date I am regularly calling to their customer service at [protected] and talk to Floor Supervisor Mr. Chander Kant but till time again nothing is happens as they are refusing to confirm for any payments made in this regard.
