I have booked flight Delhi to kozhikode through the app after money is debited from a/c but the ticket is not received and process of payment shows cancel the payment. Goibibo travel agent didn't refund the money and money is credited in their A/c as per bank statement says, the amount is credited to their bank and they didn't issue for refund to recipient A/c. They says it takes 7 working days to refund the amount till now, I didn't get any refund from their side.
