If your Campaign delivers an impression amount lower than what you budgeted for, the platform will automatically refund the amount that was not delivered to your credit card after the Campaign has ended.
If your campaign has not yet ended you can extend you bookings end date to allow more days for your campaign to deliver more impressions.
In the event of under delivery of impressions, the value of non-delivered impressions will be calculated and refunded automatically. Please note that the validity period of the credit card used to purchase the Campaigns should cover the whole delivery period for all Campaigns that were part of the booking, as refunds can only be issued for the same card used for paying for the campaigns.
Refunds can take up to 2-5 business days to complete.
Please check the Terms and Conditions for details about Nine Ad Manager refund policy.
