Has anyone successfully used DCB in Emirates website for ticket booking? Website lists diners as accepted card. It uses Cc Avenue as payment gateway and it just bounce back with message bank has declined without even going to OTP page. Card is not blocked. I have enough limit and all transactions enabled. I thought It may be because of the higher amount but the same error happens even when you add the CC to saved payment method. Surprisingly, I tried with Regalia and it is validated successfully. Anyone has any idea as it is frustrating with Diners?
