Hi, you can initiate this yourself: https://repost.aws/knowledge-center/close-aws-account

Hope it helps ;)

Please follow the steps in the following document to cancel your account.
https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/close-account.html#closing-the-account

You can close your account via the AWS Management Console.

If you do not have access to the Console, you can open up a case with this form.
