Air India — refund not initiated since last 20 days.

This is in reference to the pnr z2h6r. A day before the final departure air india failed to provide me the booked flight and finally suggested a full refund.

Its been more than 20 days, i am calling on the customer care and dropping mails to their grievance. But nobody responds. The amount is more than 50k inr. And due to their lousy behavior, i am going to miss my credit card payment deadline, which will cause me penalties.

Please initiate the refund and asap.
