I can no longer use Check Pay for my Citibank account. I have used it previously for over 1 year. For the several weeks, Check Pay is not available, only Quick Pay. When I click on Check Pay it says no account has been enabled (even though it has been enabled in the past). It then asks me to pick an account to enable and when I select the same account that has been enabled before it says "Could not enable account for Check Pay". Is there a way to resolve this issue?
