But the transaction was failed and the ticket is not booked, but the amount is deducted from my account . After the failed transaction I have got an E mail from Air vistara with an order No.[protected] and CCavenue ref number: CCAHG1RLW236.
A complaint was registered by me in SBI and CCAvenue about the failed transaction. Accordingly, the two institutions have confirmed that the payment was completed and the amount is reflected in merchant account. But till date i haven't got the refund from Air Vistara.

Copy of the E-mail and sms reply of the institutions are attached herewith for reference.

Hence, it is requested to do needful to refund my money at the earliest please.
