API Access Blocked Due to Disputed Unauthorized Usage

Hello, my OpenAI API key was apparently compromised and used by an unauthorized third party (OpenClaw-related activity). I immediately revoked the key, changed my password, and opened a support ticket with all the evidence. The issue is now under review, but my API account is currently unusable due to an “exceeded quota” / billing error caused by the disputed charges. I run a production SaaS platform, so the API outage is having a significant impact on my customers. Has anyone experienced a similar situation? How long did OpenAI take to review the case, and is there any way to restore API access while the investigation is ongoing? Thank you.
