Unable to add payment in App Store.

You should never reveal your card number on a public forum. I will ask the moderators to remove it. Sorry I don't know the answer to your question, but you can contact Apple directly by clicking on Contact Support at upper right corner of any forum page.

This is a forum for Apple users sponsored by Apple. The helpers here are all volunteers. It is not a chat site and Apple is not here unless you contact them by the means I described in another post. Good Luck!

You are welcome! Just be careful about the information you reveal online. There are lots of bad guys out there...
