Jet Airways — tickets booked on jet airways never got booked but money was debited from me.

Address:

560029

I booked a return ticket bangalore-guwahati on the 13th of march on the jet airways official app. I was charged a sum of almost 12'000/- and the same was duly paid by me and received by jet airways. On payment, the tickets never got booked. I didn't receive any ticket or pnr or any confirmation.
On calling the jet airways so called customer care i was told that the payment was received but the ticket was not generated due to a technical fault at their end and that the amount would be refunded within 7 working days. After 7 working days, there was no clue of the refund. I was asked to send a mail to jet airways. The reply to the mail said that my card was not charged and that any debits will be refunded in 10 working days. This in spite of the fact that i had not paid by card but by upi i. E google pay. I had sent them details of the payment as well.in spite of my innumerable queries, they refuse to reply to my emails nor do i have any help form their customer care. As of now it is past 15 working days and there is absolutely no refund or any correspondence from jet airways.

I would like to lodge a complaint on the american and would need help in doing so.
