Apologize for the unexpected charge. We are working on making it very clear when you will be charged for a service. (especially for non-Microsoft offerings such as MySQL DB, that are allowed to be created through Azure Marketplace) Please open a support ticket to resolve the unexpected charge.

I have signed up for a free 12 months trial to play around and see what AZURE is. Then I have received emails confirming that my subscription and data will be deleted. Now after 2 months my credit card has been charged with $1500 and a further $1800 pending. I have not signed up for any chargeable services or I have been informed about the charges. I felt save as this is Microsoft but this experience feels more like a big SCAM with the FREE Azure 12 months Trial. I don't even know how to pay the $1500! I really hope that this can be resolved.
