Summary of the bug:
I ran a sponsor on the game with a start Date of Jan 05 2024 and an incorrectly set end date for Feb 06 2024. After realizing the error I tried to cancel the active sponsor which then I found myself unable to do so.
Ad Type: Sponsored Ad through Ads Manager Campaign ID: 612ca4db-d5d0-4fef-a8e0-860412d11aca
Sponsored Ad Campaign ran under Roblox account: SmokeyDev - Roblox
@gionique Thank you for the quick fix! You all are awesome!
@SsmokeyDev ran the ad on his end. It sounds like the ad has been disabled and he can’t re-enable it anymore. Does he get those ad credits back to his account now that it was disabled?
Also I have an answer to your other question as well
Unspent ad credits get refunded within 24-48 hours after the campaign ends. Ad credit campaigns can also be canceled 6+ hours before the campaign start date to receive a refund. For more info please visit: Ads Manager | Documentation - Roblox Creator Hub
