Hello,
I was booking a ticket using my SBI credit card in the happyeasgo application and entered all the details and entered the otp for booking the flight but there showed some error and ticket was not booked but money was deducted. Then I received a mail that to book the ticket on the same locked price I need to do the payment before a time period of some 15-20 min. window. PFA the screenshot of the mail I received but due to lack of balance in my credit card I booked the ticket from some other source/agent since money was deducted by happyeasygo . I tried to call on their customer number and even mailed them on their registered customer support mail i'd but there was also no response. I was booking the ticket on 27 december for the flight date of 2nd january 2023. Kindly help me in getting the refund. Thank you.
