Licensee Ethics

[Christopher Goldie]

Question, I recently placed a property under contract. The owner calls the day before closing wanting out. 2 days later I see the property listed on the MLS. At this point I have not agreed to release the owner from our agreement. I called the listing agent and after speaking with her I have a strong suspicion that she convinced the owner to back out so she could take the listing. And the property is now pending contract.

Now strictly for educational purposes, did she violate any code of ethics? Is it worth filing a complaint or rocking the boat?
