Unknown billing charge on my bank statement: "AWS ST HELIER GB"

I understand your concern about finding an unknown AWS charge on your bank statement. The "AWS ST HELIER GB" charge indicates a payment to Amazon Web Services, with the transaction processed through their office in St. Helier, Jersey (Channel Islands).

To identify what this charge is for, here are the steps you can take:

1. Log into your AWS account and check the Billing Dashboard to see which services are incurring charges. This will help you identify any resources that may be running.

2. Use the Cost Explorer in the Billing and Cost Management console to get a detailed breakdown of which specific resources generated the costs.

3. Check all AWS regions in your account, as you might have resources running in regions you don't typically use.

4. If you can't access the AWS account associated with this charge (perhaps you created an account in the past that you no longer have credentials for), you'll need to contact AWS Support directly.

5. You can contact AWS Billing Support without logging in by using their account and billing support form. When contacting them, provide as much information as possible, including:

• The email address you believe is associated with the account
• The name on the account
• The billing address
• The amount and date of the charge

AWS Support can help investigate the charge and assist you in resolving the issue, whether it's helping you regain access to an account or identifying what services are generating the charges.
