GoAir — never received confirmation - need refund.

This is to bring to your notice about a recent bad experience i have gone through:

I am a frequent traveller of go air, in the month of november, i booked a flight from bangalore to nagpur through go air website - pnr o6p8fz & flight number 812.
After booking i didn't get any message confirmation neither i received any mail confirmation assuming that my tickets didn't get booked. I checked all folders.

After few days, as i thought the earlier ticket was not booked, i booked another ticket via goibibo that too goair bangalore to nagpur for a different date which got booked and i got mail confirmation via sms and mail both. Flight details - pnr - d1bhpl and flight number - g8812

Suddenly a few days back i received a mail from goair stating that the flight (Pnr o6p8fz) is rescheduled (Which i assumed didn't get booked as i did not get any confirmation from your end then), i immediately called your customer care and told him all the history and requested to refund the money full amount but unfortunately i didn't get much help rather he was asking me to pay extra amount for rescheduling the same flight. This is not the kind of support i was expecting from a well-known brand.

My concern is being a frequent and loyal customer of goair, i have paid twice, now i have two tickets same destination with different dates one on 31st and one on 5th.

This is a very pathetic situation and experience i am facing for the first time with goair, hope you will take this concern while understanding my situation. Expecting to get a well-balanced resolution from goair.

Please reply asap, as a flight is on 31st march 2018
