Billdesk — Amount deducted but payment status is shown as not paid

I payed 250 rupees through Billdesk for AFCAT(1)2021 cycle via google pay. The amount was debited from my account but the webpage remained un responsive and the payment status never reflected in the website.
The amount debited in the first attempt from my bank.
Kindly refund me my money back that I paid via. google pay at the earliest.
The google pay payment receipt has been attached with the complaint.
