Codex Pro 5x quota drains while idle after renewal, plus possible early subscription end

I am a ChatGPT Pro / Codex Pro 5x subscriber.

On June 25, 2026 (Asia/Shanghai), my previous Pro 5x subscription appeared to end unexpectedly even though I believe it should still have had about one week remaining. Because I rely on Codex for work, I paid again for the $100 Pro 5x plan.

After renewing, my Codex usage started draining abnormally while I was barely using Codex. In one afternoon, my weekly usage dropped by nearly 30%, and my 5-hour usage was also almost exhausted.

I checked ChatGPT/Codex sessions, devices, login activity, and running tasks, but I did not find abnormal logins, unknown devices, active Codex tasks, or background work that could explain this usage.

I also opened a GitHub issue with more details:

I have already contacted OpenAI Help Center, but so far I only received automated replies. I need a human review from OpenAI staff.

Please investigate:

  1. why my previous Pro 5x subscription appears to have ended early;
  2. why my Codex quota drained while idle after renewal;
  3. whether my incorrectly consumed quota can be restored;
  4. whether the lost Pro 5x subscription time or duplicate renewal can be compensated.

This is a serious paid-plan reliability and billing issue, not just a normal rate-limit complaint.

Drained while idle?

@OpenAI_Support I guess that is for you.

Err I am just curious, but why are you pointing out the time like β€œOn June 25, 2026 (Asia/Shanghai)”? Where are you from?
