I paid SBI CC bill on HDFC billpay (BBPSBILLPAY). The transaction was successful and received confirmation on 5 Aug 2 PM. But on 6 Aug 12:30PM received message that billpay failed. reason given is "technical issue at biller's end". i am yet to receive the refund.
is it best to wait for refund or retry payment again now? not sure when i will get refund. i still have time for due date.
