So, please explain something to me. You are saying that those features are no longer available and yet your own website located at SpaceMonger: Scan, map and manage disk drive space (stardock.com) still specifically says;
Quickly free up storage space on PCs, network and OneDrive cloud storage.
So please explain to me why you are still selling this software with OneDrive access as a listed feature? Something that, based on the above information, has been unavailable since Jan 2019 (2 years ago). You do realize you are breaking laws by doing that. It is a crime to defraud customers. It is also considered false advertising. Based on the fact that you are STILL selling it without removing advertising of said features, I expect some serious compensation. With that said, I have saved a copy of the webpage in question, a copy of the above response on 12/27/2020, and a copy of this post. If I do not receive a satisfactory response, I will file a complaint with the Washington State Attorney Generals office, the Federal Trade Commission, the BBB, and the Consumer Financial Protection Bureau.
