3 days grace is there. Better pay by tomorrow itself if it doesn't gets successful at CRED and reflect in Axis card. From next time onwards, try to pay atleast 5-7 days in advance so that even if your txn fails at BBPS sites/apps you get refund in time and make payment again in case of funds shortage.
As @desiviru suggested make payment by today only via Axis bank A/c, if you don't have then via BBPS or by directly crediting to your cc A/c via personalised UPI ID (instant credit) and if somehow the amount will get credited twice, then ask to refund to your bank A/c.
