I am trying to pay the (ISC)² Certification Annual Maintenance Fee (January 01, 2021 - December 31, 2021) of $125.00 via my credit card but every time I try it, it gives me "Error. Please try again" message.
Seems I am having a similar problem. Tried paying using my wife credit card but received the same error message.
Were you able to resolve the issue? please assist.
