I am trying to get access to my Windows Azure Portal. Although I can access my user profile which shows two active subscriptions, I cannot access the portal (https://manage.windowsazure.com/). I get redirected to this site: https://manage.windowsazure.com/Error/NoSubscriptions, saying

We were unable to find any subscriptions associated with your account.

Now, this is a clear issue for the Azure support, but unfortunately, as azure thinks I don't have any subscriptions, I cannot get support, either, because I get redirected to the same error page.

I've spent two hours talking and chatting with incompetent support people, i.e.:

I've submitted feedback on the azure site but have no idea whether I will ever get a response.

Maybe somebody has had this issue before, or can hint me which way to go?
