Greetings,
I'm not sure how this may turn out, but here:
Gather Documentation: Collect any documentation to support your case.
Contact Google Support:
You can use the Google Workspace Admin Help page.
Navigate to Billing & Payments or use their Contact Us form.
Alternatively, use the Google Workspace support feature from your admin console to initiate a chat or call.
Request a Waiver: In your email or support request, do explain the situation clearly.
Hope for the best.
