Why Am I Still Being Charged After Closing All My AWS Services?

It's easy to overlook things that lead to charges, like EBS snapshots or RDS backups, even after you've closed out services. These can linger and still rack up costs. Managed Prefix Lists can’t be deleted if they’re in use, so check if any security groups or shared resources are linked to them. You might want to look at AWS Cost Explorer to pinpoint the source of your charges.

Managed Prefix Lists are AWS's way of helping with things like Gateway endpoints, and you shouldn't be charged for them. If you’re seeing unexpected charges, it's a good idea to dive deep into Cost Explorer. It usually reveals what you're really paying for, which might not be immediately obvious.

Sorry to hear about the billing issues! I recommend reaching out directly to AWS Account and Billing Support. They can help you sort through the charges and even assist you with any urgent queries via phone or chat support if needed. Just create a case through their support center.
