It isn't the kind of experience we want you to come across, 

As I check, the investigation about Bill Pay is already closed. Since you're still experiencing the same issue, I'd suggest reaching out to our phone support team so we can investigate this further.

You can reach out to them through the ? Help icon. 

Once the issue is resolved, you can browse this page for managing your expenses: Enter and manage bills and bill payments in QuickBooks Online.

You can always post in the forum if any concerns with your QuickBooks account.
