Once you cancel your subscription in QuickBooks, the refund will be processed 7-10 days after full verification.
For more information about the refund request, I'd suggest contacting our Customer Support Team. They can pull up your account in a secure session and can trace the refund transaction for you.
Here's how to connect with us:
Click Help inside QuickBooks Online.
Select Contact Us.
Enter "Subscription refund" in the description box, then click Let's talk.
Select either Start messaging or Get a callback.
