Formal Complaint: Paid Gemini API Unusable Despite Active Billing

Google AI Studio

Dear Google AI Studio Support Team,

I am submitting a formal complaint regarding my paid Gemini API service.

Since October 29, 2026, I have repeatedly received the error “An internal error has occurred” whenever I connect my paid API key to Google AI Studio Playground.

My billing account is active, my project is on Tier 1, and I have sufficient prepaid credits.

The issue persists even when starting a completely new conversation and sending a simple “Hello” message. However, the Playground works without the paid API key.

Project ID: gen-lang-client-06302754..
API key ending: 7Hi8

I have spent considerable time troubleshooting this issue without success.

I request that Google:

  1. Investigate the cause of these failures.
  2. Restore access to my paid API service.
  3. Explain why the service is failing despite active billing.
  4. Consider refunding my unused prepaid credits if the issue cannot be resolved.

Please escalate this issue to the appropriate technical support team.

I would appreciate a substantive response rather than generic troubleshooting instructions.

Sincerely,
A Google AI Studio User
