Thank you for the reply.
I have used all my $200 credit from the first 30day period of my trial.
I think I have figured out why I am being charged :). I'm playing around with Azure for simple web hosting. With the help of App Service pricing I noticed the Pricing Plan my App Service was on was Standard. This is not free. I have since changed it to the Free pricing plan from the portal. Now my forcasted costs are more what I expected.
