Gemini API Refund Accidental Purchase

Hello Google Support,

I would like to request a refund for an accidental credit purchase on my Google AI Studio Billing account.

Billing Account ID: 01EDD2-759C5B-2FF..
Amount: $30.00 USD
Usage: The credits are completely unused — no API requests have been made and the balance is untouched.

This was a mistaken purchase. I would appreciate it if you could cancel this transaction and refund the amount to my original payment method.

Thank you for your help.
