Stacy, you mentioned "they were not able to and refunded my purchase", does it mean they were not able to install it and had already refunded your purchase? If so, it can take 5-7 business days for it to process.
Otherwise, you need to talk to support. This is community forum, no one here can handle such request.
When you talk to support, explain it and see what they say because normally Windows license is not refundable, but exceptional situations might be considered by them.
To get help, open the "Get Help" app on your computer (just search for it in the Start menu). or go to https://support.microsoft.com/contactus, Type "Billing" and press Enter. On the next screen, click "Contact support" at the bottom of the page, then choose "Windows" > "Manage my subscription". You’ll then see the option to chat with a Microsoft support agent who has access to your account to help review the issue.
