Billdesk — IB ACIO 2021 payment made twice , refund related

I had submitted my IB ACIO 2021 application form on 9th Jan 2020. I made payment twice through sbi net banking and then by sbi debit card.
First transaction was showing completed through bank but payment status on IB ACIO site was pending.
Second time (through Debit card) when I made payment then it was successful

Please refund my first transaction amount.
