Codex Credits Balance Does Not Match Usage History – No Resolution from Support

I am posting here because I have been unable to get a meaningful response through OpenAI Support.

I purchased A$15 worth of Codex credits, which provided 250 credits.

However, my current credits balance is now showing 0 credits remaining.

The problem is that the Credits Usage History page only shows the following usage events:

  • Extension: 103.981 credits
  • Extension: 1.946 credits

Total displayed usage: 105.927 credits.

Based on the usage history shown in the Codex app, I should still have a significant number of credits remaining. Instead, my balance has been reduced to 0 credits.

I contacted OpenAI Support multiple times and provided screenshots of:

  • The purchase confirmation (250 credits)
  • Credits Usage History
  • Current balance showing 0 credits

Unfortunately, the responses I received only discussed ChatGPT usage limits and 5-hour reset windows, which are unrelated to my issue.

My concern is not about ChatGPT usage limits.

My concern is that the displayed credits balance does not reconcile with the displayed credits usage history.

I have asked Support to investigate whether:

  • There are additional credits consumption records not shown in the Credits Usage History page.
  • There is an issue with the Codex billing or credits accounting system.
  • Credits were deducted without corresponding usage records being displayed.

So far, I have not received an explanation of where the missing credits went, nor have I received a response from a billing specialist.

Has anyone experienced a similar issue with Codex credits?

I would appreciate if someone from OpenAI could review this case or advise how to get it escalated to the appropriate billing team.

Thank you.
