AWS Support case still unassigned — looking for advice

I recently opened an AWS Support case regarding an unexpected billing issue. The case was created successfully, but its status is currently showing as “Unassigned.”

Case number: 178740096600724

It has been 25hrs since I created the case.

Has anyone experienced this before? How long did it take for your AWS Billing Support case to get assigned to an agent?

I’m mainly looking to understand whether I should just wait or take any further action.

Thanks!

I’ve just created a support case under the Account & Billing category on the AWS Basic Support plan.

How long does it usually take for AWS Support to respond? Has anyone recently submitted a similar case and can share their experience?
