Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi ,
In this case, I know that there are conditions for a refund for the Office 365 subscription. In this situation, I recommend contacting Microsoft support via chat to see if a refund is possible. I cannot say for sure.
The best way to contact Microsoft using the Home chat, access the link below and write "Office" below there will be a Contact Support option.
Enter your details to open the chat and a Microsoft agent will come to assist you.

If this helped, please confirm the answer or not to help other users if it helped.
Thanks
