A question related to AWS and cancellation

[ArataWata]

I tried asking this a while ago, but didn't really get much of a reply to it, anyways.

Let's say that the 12 month free trial is close to it's end and I want to stop the instance or service in order to stop myself from being charged.

Is there anyway to cancel it?

Question.

Let's say that the free 12 months is close to running out.

How would I cancel the instance to prevent myself from being charged?

I think you close your account.
