Thanks for reaching out to the Community, jakobox. I want to make sure you'll be guided to the right support.
I'd like to check this for you and get it taken care of myself. However, as much as I would like to get this handled directly, the case number requires pulling up your account information, which I am unable to do in this public forum.
I know you've already called in. However, I still suggest getting in touch with our QuickBooks Online Support to have your case number re-investigated. A phone agent has the appropriate looks, like screen sharing, and help you sort everything out.
You can use our live messaging option from 6:00 AM to 6:00 PM on weekdays and 6:00 AM until 3:00 PM on Saturdays. To ensure we address your concern on time, check out our support hours. Here's how to get in touch or chat with us:
1. Click the Help (?) icon.
2. Choose Contact Us.
3. Enter a brief description of your situation in the What can we help you with? area, then click Let's talk.
4. You'll be presented with a few options for connecting with Intuit. Select Chat with us.
I'll be sharing with you the references below. These articles contain more details on how to handle locked out accounts as well as ways on recovering when you can't sign into QuickBooks Online:
Thank you for the detailed instructions on how to contact support.
In fact, those are about exactly the same steps I used to contact support last time. The result was a several hour long chat, a promise for a followup, and now 3 weeks of waiting for that followup. So I think it's fair to say that the solution you provided is not the correct one :)
Can you please just help me troubleshoot how to log in directly to my account?
