Welcome to the QuickBooks Community, @Roark.

It appears that you've expressed a similar concern to which my colleague responded. Please visit this link to see his suggested resolution: https://quickbooks.intuit.com/learn-support/en-us/account-management/re-intuit-account-disappeared-a....

Feel free to reach out back to us if you need further assistance accessing your account. The Community team is always here to help. Stay safe.

I just called support that is listed on the page you linked, which says it's open Saturday 6 a.m. to 3 p.m. PST, and I got a recording saying to call back during business hours. So is it NOT open on Saturday? 

I can see the importance of knowing when's the best time to call our representative, Roark. 

If you're using Plus, Essentials, or Simple Start, the available hours of our support are from Monday to Friday from 6 AM to 6 PM PT. On the other hand, if you're using the Advanced subscription, you can call our support from Monday to Friday from 6 AM to 6 PM, and on Saturday from 6 AM to 3 PM PT. 

You can access this website to view more about the available hours of our support and how to contact them: QuickBooks Online Support. 

Additionally, you can also visit this material to learn what to do if you can't sign in to your QuickBooks products: Recover your Intuit Account if you can’t sign in.
