I want to make sure you can talk to one of our live agents, @helen-tierramar-.
Our customer support team will callback once you've requested. In your case, you may be requested a call back beyond our support hours that's why you haven't received any callback. Please know that our support team will only call back during their support hours (8:30 am to 6:30 pm, AEDT).
However, you can still contact them through chat since they're still available until 10:00 pm, AEDT. To do so, follow the steps below:
Sign in to your QuickBooks Online account.
Click the Help button.
In the QuickBooks Assistance chatbox, enter the topic you need help with.
Select Contact Us, then choose Start a chart.
Meanwhile, you can also post your questions here in the QuickBooks Community. I can answer some general questions or concerns about QuickBooks Online (QBO). I'm ready to help you with any questions you may have.
