Read before this
Read these direct prerequisites in order. Each guide lists any earlier context it assumes.
Use this guide when
Use this guide when credits were charged for failed work; you want a purchase or unwanted renewal reviewed; or Support approved a refund that has not arrived. Every request is reviewed case by case. Submitting complete information does not guarantee a refund or credit restoration.
Before you start
Preserve the affected project or conversation and stop repeating a charged operation. Confirm the active account or team. Open Usage for a credit event and Billing & Pricing → Invoices for a purchase or renewal record.
Gather the right evidence
- Failed or incomplete work: project or conversation URL, approximate time and timezone, final visible status or error, browser, whether one retry was attempted, and the matching Usage description and amount.
- Purchase or unwanted renewal: transaction date, amount, plan or credit-pack name, and invoice or receipt reference.
- Approved refund not received: the date Support confirmed it was issued and the non-sensitive transaction reference.
Send the request
- Open Support from the Studio navigation when it is available. Otherwise open the ngram contact form and choose Technical Support.
- State whether the request concerns failed work, a purchase, an unwanted renewal, or a previously approved refund.
- Add only the matching evidence listed above and describe the outcome you are requesting.
- Keep the project and records available until Support completes the review.
What happens next
Support reviews the request and confirms the outcome. Do not treat an acknowledgement as approval. If Support confirms that a refund was issued, allow 5–10 business days for the original payment method to receive it, then follow up with the existing request if it is still missing.
What not to send
Never send a password, API key, access token, full card number, bank login, or unrelated private source material. A receipt or invoice reference is enough unless Support requests another approved form of evidence.
