In the United States, you can sue John Doe (the anonymous party who created the listing) for identity fraud and trademark abuse, and then file a discovery motion compelling Google to divulge their identity so that they can be identified and prosecuted by the court, with your lawyer optionally noting to the court that Google removing the domain from the other entity as you originally requested (and paying your court costs and lawyer fees as damages, as they were notified of the fraud and refused to act) would be an acceptable settlement. In the United Kingdom, you can sue Google for libel, as their misrepresentation of someone else as you harms you, and if you prove malice ('reckless disregard for the truth', which Google is clearly demonstrating) you can not only compel Google to remove the libelous material but also win damages from Google for their flagrant disregard for the truth. What jurisdiction are you in?
