Not sure what you mean by scam, we're an official Ubisoft retailer working with the publisher for many years - https://www.ubisoft.com/en-us/help/ubisoft-store/connectivity-and-performance/article/approved-digital-distributors-of-ubisoft-games/000079502

Seems you haven't activated the game on your ubisoft account yet, would try another browser and making sure you have no addons on. If you still have issues please email [email protected]
