Developer Support not available?

Does anyone know how to contact Developer Support?
Trying to change my address as I moved to another country last year. The phone numbers only show "not available" and my emails support with the address change (8 of them since November) are unanswered and still no changes. Any help would be nice.
Did you use the Contact Us below ?
https://developer.apple.com/contact/

They usually answer pretty fast.
Yes I did I have 5 case numbers from November but never an update/reply
