Billdesk — Afcat refund not received

On 2/1/2021, I paid for Afcat 1 2021 in google pay through bill desk.
The money has been deducted from the account but the payment process is incomplete.
I paid again through debit card and that process is successfully completed.
But there is a delay in refund for the first payment.
So I request to see through this problem and solve it
