Billdesk — Regarding SBI PO Payment

For SBI PO exam 2020. i paid the fee via Internet Banking. Cash transfered from my account to IBPSBILLDESK on 04/12/2020. But In IBPS application website shows like "your previous transection failed". i didn't get any updated status from either bank balance or sbi po 2020 exam webpage. After 3 hours I made another payment that worked fine and got successful message.
Requesting first payment status and refundable date.
