Consumer Redressal

Hi, I had booked indigo flight from Raipur to Bangalore (PNR D1TFTP) in Oct 2013 for three adults and one child. I paid the charges using American express credit card (amount 14000 INR) and using Indigo vouchers (amount 16000 INR). I cancelled one ticket for one passenger from this itinerary (pnr G366PW). At the time of cancelling, I was informed that 6500 INR would be refunded to my credit card account. I followed up on the cancellation in Nov and again in Dec and each time I was promised by call center executive that amount will be refunded soon in my credit card account. On 18th Jan 2014, when I called indigo customer care to follow up on payment, I was informed that there will not be any refund since payment was made using mix of voucher and cash/credit card. This process is quite unreasonable, since I paid about 14k INR using my credit card, the required amount must be refunded. Request you to take up this matter with the Airline.
