I worked for the feds in an Ombudsman's office where we handled/processed complaints from consumers. (not IRS related)
The complaints we received that were sent through Congressional offices got special treatment.
In addition to speaking with the Taxpayer Advocate Office, I would suggest that you file complaints with your Congressional representatives. They have had hearings in the past about what IRS is doing to citizens. I think that is how the Advocate office got started. Congress needs to know what IRS agents are doing to us.
