Go Air — complaint

This is regarding my booking with pnr j2wzvi of flight g8 803 from port blair to bengaluru on 01 oct 17. The flight was in the name of mrs sugandh sharma, who is my wife. The mobile number and email id used for the booking was - [protected] and [protected]@gmail.com. The booking date was 21 august. The mode of payment was online banking which was declined. However the amount was deducted from my account on 22 august and a refund has not been initiated till date. Also, since the payment was declined and the booking was cancelled, i did not receive any confirmation or information regarding the same. It happens to be by chance that i checked the status a day prior that i got to know that the payment was declined and still pending that i called the customer care. The customer care representative informed me that my ticket has been cancelled.
It was their duty to inform a customer if his ticket has been cancelled. What if i had not checked and reached the airport only to find out that the ticket has been cancelled? Also it has been over a month that the amount has been deducted from my account but no refund has been initiated.
Secondly because of errors from their side i had to re book a ticket on the next day (2 october) with pnr ddjt9b, whose fare is rs 11299/- whereas the original fare for pnr j2wzvi was only rs 9979/-. Their inefficiency and unprofessional attitude has costed me extra money.
I wrote it in a mail and sent it to [protected]@goair.in and sent the mail twice on 30 sep 17 and 03 oct 17. However, there was no reply from their end and they ignored me completely.
