I don't use any of 'EC2 instance', why do I pay?

Question

Hello guys.

in this year of may, I have created two EC2 instance to learn about redis & elastic search.

sadly I failed, so I deleted all of instance two months ago.

However, Why do I keep getting 85% usage notifications when I haven't created any instances in 2 months?

Answer

Hello.  
Have you verified that all resources are not left?  
Also, have you checked your bill to see which services you are being charged for?  
If you are able to identify which AWS service is being charged for by checking your bill, delete or stop the service.  
Active AWS services can be verified by following the steps in the following document.
