Credit Card Payment Blocks

Here's a tricky one that Ad Center have really got to sort out ASAP. In AdCenter you have multiple accounts each with their own payment options. These accounts can represent different departments within your company or if you’re an agency, different clients.
In my case I am beta testing three clients, each with their own credit card details. The credit card for one of these clients reached its limit this morning and AdCenter sent me a very nice e-mail letting me know that the account is past due.


"Your orders have been paused and you cannot create new orders or change existing ones until your payment has been received." Nothing unusual or unreasonable in that.
When I log in to AdCenter to update the credit card details with another card provided by my client, what do I find?


ALL MY ACCOUNTS HAVE BEEN PUT ON HOLD!


So if one of my clients has a credit card issue, it would seem that all of my clients are put on hold until the issue is resolved. As an agency, I can't imagine having to explain to client X that his account has been put on hold because Client Y hasn’t paid his bill!!!!!
Owch!
