I have followed the instructions here - http://azure.microsoft.com/en-us/documentation/articles/azure-web-sites-web-hosting-plans-in-depth-overview/. I have emptied the web hosting plan, I can't delete the websites as they are live, so I have moved them to another web hosting plan. When I try to delete the hosting plan I get the following error;
Failed to delete web hosting plan : There was an error processing your request. Please try again in a few moments.
I have waited over an hour now, and I still get the same error.
