[Resolved]  Indigo Airlines — amount taken from my bank account for ticket not issued

On 15 aug 2019 i have booked indigo chennai to doha via calicut. Pnr yfl99c i got sms that my booking was on hold. I have used my qatar credit card issued by ibq. I called the customer care number mentioned in website and enquired. They told it is not done since bank declined. They assured that money will not be taken. I used my sbi india credit card and completed booking and travelled on the same flight. I am shocked to see a debit in my ibq credit card account for rs.34, 366. Till date refund has not been made. I have already sent a mail from my mail id [protected]@gmail.com please refund this amount immediately.
