In Sequence:Same happened with me. Later I have paid the same bill with a gap of about 6 hours... It went through. Let's other clarify the exact gap needed for successful payment.
1) With HDFC - failed
2) With Indusind Signature - Successful
3) again with HDFC - failed
Just in 5 mins, 2 transactions failed and 1 was successful...
