Billing support case unassigned for 20days after CloudWatch Logs misconfiguration

I don't have specific information about your billing support case or why it remains unassigned after 20 days. However, I can provide some general guidance on AWS support cases.

Support case response times depend on your AWS Support plan level. If you have a billing-related issue, these cases are typically handled with priority regardless of your support plan, as all AWS customers have access to billing and account support.

If your support case has been unassigned for an extended period, I recommend:

1. Replying to the existing case - Add a new correspondence to your open case to bring it back to attention
2. Checking your case severity level - Ensure the case severity accurately reflects the urgency of your issue
3. Opening a new case if needed - If you're not getting a response, you can open a new billing support case
4. Contacting AWS Support directly - You can reach out through the AWS Support Center or contact methods available for your support plan

For billing issues specifically, you should have access to support regardless of whether you have a paid support plan. If there's been a misconfiguration with CloudWatch Logs that's affecting your billing, make sure to clearly describe the issue and its impact in your case correspondence.

If you continue to experience delays, you may want to escalate through your account team if you have one, or request an escalation within the support case itself.
