I have booked a flight ticket from Varanasi to Mumbai from travlook on 1st June2022 and the ticket amount of ₹8748, the amount got successfully deducted but within 5 min I got a call from customer care that due to a operational reason from airlines ticket couldn't be booked and I will get my refund in 10-15 working days.
It has been more than a month and I haven't received the payment yet. their executives are not even responding properly and they repeatedly saying refund has initiated 3 days back and money will be received after 3 to 4
