Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
In this case, try contacting the store where you received the redemption key; it is possible that it was an unofficial volume license key, so you should request a refund.
If you wish to download the software, you can download Office 365 from the link below; the setup file is the same for both Office 365 and Office 2024.

If you have questions regarding the key you redeemed, you can contact Microsoft Support.
The best way to contact Microsoft is using the Home chat. Access the link below and type "Office." Below, there will be a Contact Support option.
Enter your details to open the chat, and a Microsoft agent will assist you.
