Please escalate to the internal billing team: USD 5,230 Gemini API charges, no request records provided (Cases 72705455 / 74566968 / 75417009)

I am asking a Google staff member or forum moderator to escalate cases 72705455 / 74566968 / 75417009 to the internal billing team. Billing Support pointed me to this forum on 13 July and 22 September. I am billed through an authorized reseller in Taiwan and can DM the project ID and invoice numbers.

Facts

  • January–April 2026: the project’s total bill was USD 220–390 per month.
  • 2 May–27 June 2026: it was billed for gemini-3.1-pro on 57 consecutive days, rising day by day (May USD 963.60, June USD 4,399.51). Through my reseller, Google put the Gemini API charges for the period at USD 5,230.12 (the support case title shows USD 5,213.76).
  • Through my reseller, I disputed the charges on 29 June, before the invoice was due, and on 3 and 8 July asked for the request-level records (timestamp, source IP, credential, token count).
  • 9 July: Billing Support said it cannot provide the call details and does not know the review criteria.
  • 13 July: it pointed me to AI Studio “Logs and datasets”. On 22 September it said that feature only has records if enabled beforehand; this project has none. In the same reply it called this a product question and referred me here.
  • 8 July, 15 July, 25 August: the adjustment was rejected three times. No criteria, contractual basis or facts were stated; the 25 August reply said only that the internal engineering team had determined the usage did not meet the conditions for a billing adjustment.

So I am asked to pay USD 5,230.12 without being shown a single request behind it, and the only records are on Google’s side. If any fact above is wrong, please say which one and show the record.

What I am asking

  1. Escalation of the three cases to the internal billing team.
  2. The request records behind the charge, or a written reason why they cannot be produced.
  3. If the charge cannot be substantiated, a full reversal of USD 5,230.12 through my reseller (a refund, credit memo or credit is acceptable), as in thread 179135 (reseller-billed, fully credited in September).

Thank you.
