Hi Rebecca68,

I appreciate you coming into the Community about your bank connection. I also understand that you've already tried everything, including the steps that we can share from here. 

I recommend getting in touch with our QuickBooks Desktop Support again to check this further. But first, you'll want to access your Intuit account in CAMPS and update your profile so our Support team can see your name when they open your account. If you're not the owner, please have the owner contact the team instead. You can explain the things you've tried to avoid repeating them.

Please check out this article so you'll be guided through the said portal: Change, manage or update your Intuit account with CAMPs.

Let me know if you have any additional questions about your bank connection.
