I bought R$200 in prepaid AI Studio credits on Aug 10 and received the “your prepayment was completed” email the same day. The “Action required” email says the service resumes automatically once the prepayment processes — but it never did.
Digging in, my underlying Cloud billing account (018296-…-D8AAA2) shows as CLOSED and the “Reopen billing account” button is disabled with “account not in good standing”, even though my payments profile has zero pending issues — identity and tax info verified since Jan 2025, and the only declined charge (a R$9.99 subscription) was settled on Aug 11.
Cloud support refuses free-trial accounts, and the Payments help center has no working contact path. The API returns free_tier limit: 0 for all image models.
How can I get the billing account reopened (or the prepayment refunded)?
