Also, there's nobody to contact at Microsoft regarding Azure billing. I was prototyping some app that used App Service, Document DB, and Notification Hub and for a few months they billed at around $10 - $20, all of a sudden it's $1,200 for a month. The app was not launched, I was the only user. There's no way to figure out why other than it's a DocumentDB charge. There's no way I'd put anything in production with Azure.
