Last week I tried to change my payment info with changing credit card number. It wasn't possible. I received a message: "There is a problem with the card information entered here. Please review and try again. If the problem persists, please contact customer support." I checked my card and its all data and it was surely OK. I also read some help informations on http://helpx.adobe.com/pl/x-productkb/policy-pricing/membership-subscription-troubleshooti ng-creative-cloud.html#creditcard.
I tried to do that in different environment (Windows, Mac, Firefox, Safari, Chrome). No effect.
What is interesting, today I received an email with information about failed payment process (although I finally didn't change my credit card). My current credit card is active.
As a result, I can't change my payment info and also I can't pay for the subscription.
Please, check this issue.
I have problems as well. I've updated my payment info a week ago, there are enough funds on the card. I'm still getting a warning that my subscription will shut down. I have only one day left. And the worst part is - there is no way to directly contact Adobe about this. The only "contact" they offer is a FAQ and this forum. This is insane.
