I will call billing. I used a Mastercard. The same one I have been using for years. And it is the same one I use with my other account. That one is as Vickie Wunderland. And that seems to be still working.
I signed up with the new system and made my payment. It was rejected but it will not say why. I can't fix it if I don't know what you did. I have two accounts and so far I have not had a problem with the other account. Yet.
