I'm sorry but this is a bit too vague to answer. It is not clear to me if your issue is with HUD the agency or if you need to contact the agency because the issue concerns your housing situation. You mention a previous question, but I don't know that I saw that on here. I am responding now because you posted 2 days ago and have not response which makes me think the other attorneys are similarly confused.
If you don't want to re-post, I would suggest starting with Legal Aid if this is about Section 8 issue, the attorney general of State of Wisconsin's consumer complaint line if this is about a rental issue, or an attorney if this is about a mortgage.
I hope this helps.
My response to this question does not create an attorney-client relationship and does not consitute legal advice. The information is provided as a courtesy only. This format of written question and answer is too informal and lacks sufficient detail. It is almost never possible to give quality legal advice without a full set of facts and the opporutnity to have a dialog where questions are asked and answered. Moveover, posters on the internet should be aware that confidentiality is not guaranteed online. I am licensed to practice law in WI and IN.
