It depends. Were you working at the ad agency when you created the logo? It’s not clear from your wording. If so, the 3d logo was done as “work for hire”, meaning the agency owns anything you created while working for them (as an employee, is what I mean).
If the 3D logo was created as a freelance employer for the ad agency, and you billed them for the initial project (of which the 3d logo was part), and you didn’t stipulate in the contract that usage of the logo was granted only as part of an ongoing campaign, or was licensed to the agency on a per commercial basis, you probably don’t gave a strong case. It would have to be clear that the logo was only licensed for the one commercial (much the way music has a needle drop license).
Either way, you most likely won’t do any more work for the agency if you send them a bill. You’re better off calling the Art Director (or whoever the project manager was), and voicing your dismay, rather than just sending a bill. You’ll come off as more professional, and keep the door open for future work, no matter how the dice roll. Good luck!
