Hi Dave, in this case, you must contact Microsoft to get a refund since this is a user-to-user support forum. I leave the steps below:
"Please get in touch with Microsoft Support for further help.
Please go to https://support.microsoft.com/contactus page
Type the ""Chat with someone"" option and press Enter.
Please click on the ""Contact support"" button at the bottom.
Select the Product and Category for support according to your requirement.
The available support methods will be shown to you.
I hope you find this information useful. If you have any more questions, don't hesitate to reach out. Otherwise, please take a moment to accept the answer. Wishing you good luck!
