Indigo Airlines — company still being careless even after complaining many times

Website: www.goindigo.in, [email protected]

The customer relations team of indigo sent me a mail giving me a rnn number for the refund of pnr-xc85sp to verify with the bank manager. I have already approached the bank more than 5 times with different reference numbers provided by indigo team but every time i get the same response from the bank that the merchant hasn't sent any amount to my account and this time also the manager verified it himself and he told me that the merchant (Indigo) has not sent any money and no such amount has ever been sent by the airlines. They are trying to cheat the customer and it has been more than one month and i am always promised a call back by the finance team of indigo but they never give a call back. I am facing a lot of problems regarding my refund. I am attaching a screenshot of the recent mail sent to me by the merchant.
