Cannot change country in my AppleID and access the developer member center.

Hi everyone,

I have a problem with my AppleID, that was created for my company email. It was needed to access the company developer portal by accepting an invite from developers member center. Now I'm not able to access the developer member center, as it states that I don't have a country in my AppleID. But I'm not able to change it simply because it writes that it cannot be changed ...

Any help? Contacting support regarding such AppleID issues is impossible - I found no way to contact them.

Thank you,

Stan
