Windows 10: Windows 11 pro upgrade refund

I just purchased windows 11 pro but i already have windows 11 . i dont want to spend 200$ rather than 100 $ for the upgrade. I have not used the product key from my purchase yet. How do i get a refund for the entire download that i spent 200$ on rather than 100 for the upgrade?

Upgrading to windows 11

I have a few questions about windows 11...

1. How many GB it is? when my pc suggested the upgrade yesterday, it said it's about 4GB just want to be sure.
   
2. I'm using a windows 10 pro so if I upgrade, will it upgrade to a windows 11 pro?
   

 

Windows 11 Home to Pro upgrade

Want to upgrade 11 Home to 11 Pro. Tried download, but apparently files transferred were for 11 Enterprise. This will not activate; error is "invalid digital license or product key". This is on a new Surface. How to proceed?

Can withdraw/delete this. The suggestion to downgrade - listed below - with a 'fake' windows 10 key works.

 

Windows 11 Pro Unable to Install - II need a refund ASAP

Windows 11 Pro Unable to Install - II need a refund ASAP on W11Pro.

I followed all directions exactly innumerable times. I believe incompatible with work system. Despite that under 'Order' - it does not give me an option to refund or replace - I find this outrageous.

I just ordered in 11/15/21.

How can I get in contact with a Microsoft Agent by phone (who cares) to assist me in getting a refund.

Any other suggestions are welcomed from Community too. Thank you!
