Cant add Credit Card: Apple Developer Support doesn't respond

I receive notifications that my developer Account will expire.

But i cant add a credit card to my account. The Button leads me to appleid.apple.com where i have no option to enter card infos.

Since then i have contacted the Developer Support per Email (developer[AT]email.apple.com) and got nothing back. After around two weeks i submited the Web Fomular on (https://developer.apple.com/support) where i got an case number 1 Week ago.

On every support topic there is no Phone number to get a call with somebody.

How do i get a credit cart in my account?
