Billdesk — RBL Credit Card Payment deducted in bank account but not credited to credit card

I have made a payment of Rs.20, 000/- on 03/08/2021 towards my RBL credit card payment via the RBL app using billdesk; REF: WHDFC[protected]-BilldkRATNAKARBANKLI, ref:[protected]; however, it showed transaction unsuccessful but payment got debited from my HDFC bank account.

Please credit this asap to my card or return to my account. I am herewith attaching my screenshot of the transactions.
