billing question

Hi,

according to this: https://repost.aws/knowledge-center/close-aws-account:

You can still sign in and file an AWS Support case, or contact Support for 90 days. After 90 days, AWS permanently deletes any content remaining in your account, and shuts down any AWS services that you didn't shut down. However, AWS might retain service attributes as long as necessary for billing and administration purposes. AWS retains your account information as described in the Privacy Notice. You can't permanently delete your account before 90 days. You can't reopen the account after 90 days.

I would suggest that unless you are not able to access your account, to contact AWS Support team.

Hope it helps ;)
