Thank you for coming back to the QuickBooks Community, Kimm5. I also appreciate you for sharing detailed information on what you've done. This isn't the kind of impression that I'd like you to have, and we know how much time it can take when something isn’t working the way you need it. This is why we make great efforts to deliver customer satisfaction at all times and to fix an issue as soon as possible.

Since you haven't still received a reply from the support, I suggest contacting them again. They have the tools to check and view the status of your request. Then, provide information on the updates.

Please refer to this article to see different banking errors and how to fix them: What to do if you get a bank error or can't download transactions in QuickBooks Online.
