HappyEasyGo — Double payment due to happyeasygo payment server issues

I have booked a flight from Bhopal to Bangalore at 15:44pm today.
In the first time, I have entered credit card details and OTP. Server showed an error message 405 (Method is not allowed or supported)
I have received a message to perform transaction again otherwise seat booking is tight. I have made another payment on the app for the same amount at 15:46pm.

Two times amount got deducted from my account for the single ticket.

Please refund the extra amount as soon as possible.

Details are as follows:
