Since December 2020, when we upgraded to Enterprise 21.0, we have been receiving Error code 9000 when we submit our payroll data.  Since December 2020, each payroll we run (13 payroll in total) we have received this error code.  Every time we speak with a QB rep, we are told time and time again several different answers- nothing is consistent with their responses.  In that time, I have spoken to Priority Circle and 15 other QB reps, but to no avail there is never a permanent solution.  I am beyond frustrated with this issue.  I spend well over 2 hours on the phone each time this happens. It even got to a point that we had to redo an entire payroll over again as I was told "this would correct the problem."   We have had our IT company make changes to firewall settings, security settings, etc. We have gone through each possible solution as suggested by QB (even including all of the above mentioned solutions in the above threads).  We even reported this via the bug report under the help menu.  We are told that QB engineers know of the issue but that there are other projects ahead of this one.  Yesterday, I was told that the QB rep could no longer stay on the phone with me as she had to get to other customers.  We should be the priority at the moment.  We are getting to the point of switching vendors as we cannot seem to get answers or resolutions.   I am hoping this goes to the top of the chain and that management or engineers get this resolved.
