Hello,
Welcome to Microsoft Q&A!
Are customers of downloadables eligible for the 30 days' Microsoft Store refund?
First of all, your issue is more related to the Microsoft Store billing.
I'd suggest you check the MICROSOFT TERMS OF SALE. In section 16, it clarifies the Return Policy. If this still can't help you, you could try the following ways:
1) You could ask your question here: Microsoft Store & billing help.
2) You could contact the Microsft Support here: Contact Microsoft Support.
3) You could contact the Microsoft Store team here: Contact Us. Go to Contact us, find Non-Technical Support - Dashboard and choose CHAT NOW or **
SUBMIT AN INCIDENT**.
Thank you.
