On Friday I had tech support help me do a refund & was told both the client & I would receive an email within 24 hours confirming it. Neither of us have received one yet

Let's check why you're unable to receive emails from Intuit, @realpurdy1.

We have to ensure you add Intuit's service email addresses in your email's list of accepted senders. 

We give services that enhance your QuickBooks Online experience. Each of our services has its email address. These service-related email addresses needs to be set as a safe sender or whitelisted on your email account to make sure you receive important communications from these services.

To ensure, you're able to get significant email from Intuit, please check this article for more details: Receive important email messages from Intuit.

If the same result happen, I recommend getting in touch with our customer support team. This way, they can further check your request refund.

Also, you may check out handy articles in our QuickBooks Help page that can guide you in managing your sales forms, running report, handling payroll, etc.
