Unexpected bills from AWS Free Tier

Hi

Some months ago  I followed some aws doc to see live streaming example. The doc was suggesting Adobe Media Server subscription. I subribed,and tried to run ec2 instance from amazon console. I could not make the instance running i thought it hangs ,and, after some hours leaved aws console because it was not seem running. After that I haven't checked any instance because i thought nothing was running.

10 days ago i tried to login aws console and i see it was suspended because of bills. When i saw unexpected bills that charged in free tier, i asked Amazon for waiving off these bills but they can do if Adobe approve it.

I haven't done any payments yet thus i asked for a waiving off.

If amazon can provide you can see the logs that the services is not used for any purpose.

Best Regards
